Mad Scientist Monster’s Masked Singer Season 13 Carnival Night Performance & Clues

Mad Scientist Monster Revealed How He Found His Purpose

Before Mad Scientist Monster came out on stage on The Masked Singer season 13’s Carnival Night, the camera zoomed in on parts of his costume, including an I.D. badge on his lab coat that at first had a picture of an orange and a peach, which referred to Florida and Georgia because of Brian’s group, Florida Georgia Line. Florida is famous for its oranges, while Georgia is known for its peaches. In his lab coat pocket, Mad Scientist Monster also had a pen with an orange decoration on top. This is because Brian is from Florida, making up the Florida half of Florida Georgia Line.

Mad Scientist Monster’s badge later had two bees in it, which referenced Florida Georgia Line’s hit with Bebe Rexha, “Meant to Be.” The two bees referenced “to be” and Bebe’s name. Mad Scientist Monster then sang a powerful rendition of “Unwell” by Matchbox Twenty.

Mad Scientist Monster began his clue package by meeting his costume. He said, “Oh, snap! You don’t look that mad to me. Becoming the Mad Scientist Monster fits perfectly for me because you have to be a little bit crazy, keep experimenting, and reinventing yourself, which is why I’m here. Let’s go win this thing.”

As the scene changed to a laboratory, Mad Scientist Monster said, “Sometimes in life, you think you have the perfect equation, that things will be simple.” He then poured a red liquid into a container. Mad Scientist Monster continued, “I was on the path to become the best in my field. My skills made the scouts go wild. It seemed like everyone wanted to recruit me to their team.” Mad Scientist Monster held a radar gun that said, “FAST,” as he said this.

Mad Scientist Monster went on to say, “But when it was time for my chance, everything combusted.” At that point a funnel of red liquid exploded in his hands. He continued, “They sidelined me. I about lost my mind. But, in the chaos, a new experiment bubbled to the surface. You see, for every action, there is a reaction.” A large fish, most likely a tarpon, then swam by in a fish tank. Brian played college baseball and was even scouted by the pros, but he switched to a music career when he was benched more than he played. The tarpon represented his home state of Florida.

Mad Scientist Monster then said, “And my reaction changed the world. I found my purpose. So, yeah, it turns out, I’m not crazy. I’m just a little, um, well, mad. So stay awhile, because there’s a high probability I’ll melt your heart.” Brian and Tyler Hubbard founded Florida Georgia Line in 2010, and music became Brian’s purpose.

After Mad Scientist Monster’s performance, another clue was revealed about his identity. He said, “You know what? This is so important to me because it gives me an opportunity to reintroduce myself to fans in a way that they’ve never seen before.”

Detective Lucky Duck then returned to give one more clue about Mad Scientist Monster. He shared, “That radar gun really threw the panel a curveball, but here’s a hint. If you’ve been listening, you’ll hear the right pitch.” These were more clues about Brian’s experience with baseball.

Mad Scientist Monster Told The Story Of How He Met His Beloved Wife

During The Masked Singer season 13 Boy Band Night, Mad Scientist Monster sang a moving version of “I Swear” by All-4-One. Mad Scientist Monster’s clue package began with him standing in front of a lake. He said, “Everybody loves a hunky boy bander, but there’s more beneath the frosted tips surface. At their core, boy bands are about chemistry. And I know a little something about that.”

The scene then switched to a forest filled with giant red and white mushrooms and a table with a Thanksgiving dinner on it. Mad Scientist Monster continued, “When I met my BOO!–ha ha ha, sorry, didn’t mean to scare you there–I’m talking about my girl. It was a festive fall evening, gathered around a full Friendsgiving table, and when our hands brushed passing the cranberry sauce, sparks flew.” He then pushed a bowl of cranberry sauce toward a picture of a female Mad Scientist Monster. Brian met his wife, Brittney Marie Cole, at a Thanksgiving dinner party.

The Masked Singer season 13 Group C contestant continued, “I swear, right then and there, I knew I’d marry that girl some day.” A grandfather clock with the hands spinning was then shown, and it also had a hand doing the thumbs-up signal at the bottom of it. The camera then zoomed in on the face of the clock, which had flowers in it. The clock and the thumbs-up symbol referred to Florida Georgia Line’s first album in 2012, Here’s to the Good Times.

Mad Scientist Monster continued, “But, seasons passed, until one sweltering summer day we reconnected, and I serenaded her until her Bunsons were burnin’.” Brian and his wife reconnected years after they first met. A sand castle was then shown. This referred to Brian’s first solo album in 2021, Sunshine State of Mind. Brian also has a song called “See You Next Summer” from his 2023 album, Tennessee Truth. Then, a cruise ship passed by blowing its horn. This was a reference to Florida Georgia Line’s first single, “Cruise.”

Mad Scientist Monster said, “I made her a promise I’d never leave her side, for better or worse.” He then blew kisses to her photograph. Mad Scientist Monster concluded by saying, “Now here’s an epic boy band love song for that woman I made a promise to–my wife.”

After Mad Scientist Monster’s performance, The Masked Singer season 5 contestant Omarion, who was Yeti brought out another clue, which was a t-shirt that said, “BTS and BSB.” Mad Scientist Monster explained, “You know what? It’s an honor to have won the same award as both Backstreet Boys and BTS.” Florida Georgia Line, Backstreet Boys, and BTS have all won American Music Awards.

In his confessional, Mad Scientist Monster continued to pay tribute to his wife. He said, “I think I made my wife proud. She’s the love of my life. She’s my greatest muse, and my best friend. And I know she’s probably back there singing along and smiling.”

Mad Scientist Monster Spoke About A Professional Split

During The Masked Singer season 13 Group C finals on Decades Night, the Group C finalists–Mad Scientist Monster, Nessy, and Yorkie–opened the show with a rocking rendition of “My Sharona” by The Knack. Mad Scientist Monster then sang a sensational version of “Love Yourself” by Justin Bieber, which he concluded with an impressive falsetto section.

During Decades Night, Mad Scientist Monster represented the 2010s. He began his clue package by saying, “Man, I chose the 2010s because they were lit. Electric cars hit the roads, and smartphones hit the stores.” Mad Scientist Monster was then shown on a smartphone getting emoji reactions. He added, “And, it’s one of the best decades of my career. It seemed like I could conquer the world.” Brian and Tyler debuted as Florida Georgia Line in 2010, and they had great success throughout the decade.

As Mad Scientist Monster was shown holding a gold trophy, he said, “I won every award possible, except that Nobel Prize.” Florida Georgia Line has won Academy of Country Music, CMT Music, CMA, American Music, Billboard Music, Teen Choice, Canadian Country Music, ACM, American Country Countdown, and iHeartRadio Music Awards. A gold sun was then shown, which was another reference to Brian’s first solo album, Sunshine State of Mind.

In addition, the sun looked very similar to The Masked Singer season 4 winner LeAnn Rimes’ Sun costume. This is because Florida Georgia Line and LeAnn both have songs on the Mötley Crüe tribute album, Nashville Outlaws. Florida Georgia Line sang “If I Die Tomorrow,” while LeAnn sang, “Smokin’ in the Boys Room.”

Mad Scientist Monster then put on a cowboy hat as he said, “But I didn’t do it alone. And, while we had a good run together, it didn’t last forever.” Florida Georgia Line has been on hiatus since 2022, and both Brian and Tyler have since begun solo careers. The cowboy hat referenced Florida Georgia Line’s country music career.

As he texted on a smartphone, Mad Scientist Monster shared, “We had very different theories on life. I wanted to explore new avenues, and keep our grand experiment going. But we never tested that hypothesis. So, I ventured out on my own.” In 2024, Brian and Tyler confirmed that Florida Georgia Line broke up because Brian wanted to start a solo career, but there’s no animosity between them. Texts that said, “You in?” and “No, thanks” were then shown, followed by a miniature model of a silver pickup truck. The truck referred to Florida Georgia Line’s 2021 album Life Rolls On.

Mad Scientist Monster went on to say, “At first, I was, well, mad. But life rolls on, and once I went out on my own, I found I quite liked that I was in control of my results. Now, I realize I learned a major lesson. Sometimes, chemistry changes. And that’s okay. And, not everybody’s gonna love ya. Well, that’s okay too. As long as you love yourself.” Mad Scientist Monster then pointed at a sign that said “Love Yourself!” in a heart. In these clues, Mad Scientist Monster actually said the title of Florida Georgia Line’s last album, Life Rolls On.

After Mad Scientist Monster’s performance, another clue was given about his identity. The Decades Night time machine brought out a clue from the 2010s, which was a DVD that had the Masked Singer logo and said, “Season 4.” Mad Scientist Monster explained, “I’ve performed with someone from season 4.” Florida Georgia Line has a song with Backstreet Boys called “God, Your Mama, and Me.” The Masked Singer season 4’s Crocodile was Backstreet Boys member, Nick Carter.

In his confessional, Mad Scientist Monster said, “You know, that falsetto … I just thought that’d be a cool moment right at the end to kinda take it to the next level, and show the judges I came here to win, so I want to stick around as long as possible.” After the audience and panelists voted, Mad Scientist Monster’s wish came true, and he made it straight through to the Lucky 6.

During The Masked Singer season 13 Lucky 6 Night, Mad Scientist Monster sang a spirited version of “There’s Nothing Holdin’ Me Back” by Shawn Mendes, during which he danced. Before his clue package began, Nick said that the panelists had guessed Blake Shelton and Keith Urban, but at least one of them was incorrect. Nick let Mad Scientist Monster explain.

Mad Scientist Monster began his clue package by saying, “If you’ve been doing your research, you’ll know I’ve basically told you everything about me. I’ve played sports, I love my wife, and I didn’t get here alone. And, while you guys are close to solving the equation, there are still holes in your theories because–spoiler alert!–I am not Keith Urban. But, we have shared a stage together.” In 2017, Florida Georgia Line and Keith Urban headlined Stagecoach Festival. They’ve also both performed at Keith’s 2023 All for the Hall fundraiser to benefit the Country Music Hall of Fame, as well as at the CMT Awards.

Mad Scientist Monster then went on to reveal a major clue about himself. He said, “Now here’s a colossal clue that’ll drive you mad.” It was a Tennessee flag. This is because Florida Georgia Line was based in Nashville. In addition, Brian’s 2024 album is titled Tennessee Truth.

After his performance, the panelists conducted a 30-second rapid-fire Q&A, which began with Ken asking Mad Scientist Monster what kind of car he drove. He responded, “A Ford Raptor, baby.” Brian drives this truck. Ken then asked him if he won any awards for singing. He answered, “Yes. Many, many of them.” This referred to Florida Georgia Line’s many awards. Ken also asked Mad Scientist Monster if he was younger than him. He replied, “Way younger.” Brian is 39, while Ken is 55.

The Masked Singer season 13 quarter finals on Soundtrack of My Life Night began with Mad Scientist Monster and his fellow Top 5 contestants–Boogie Woogie, Coral, Nessy, and Pearl–singing a fantastic rendition of “More Than a Feeling” by Boston. After the group performance, Detective Lucky Duck returned to give a clue about one of the contestants. He said, “Panel, I have uncovered something explosive about one of these famous masks. Turns out, they have stolen something very valuable from you, Robin.” Florida Georgia Line released “Cruise” when Robin released “Blurred Lines” with Pharrell Williams and T.I., and Florida Georgia Line won the American Music Award for Single of the Year in 2013, besting Robin.

Mad Scientist Monster later sang an emotional rendition of “The Scientist” by Coldplay. Mad Scientist Monster began his clue package by revealing, “The soundtrack of my life is a song that happens to be my wife’s favorite: ‘The Scientist’ by Coldplay. She loves those guys as much as she loves hearing me sing.”

Mad Scientist Monster’s wife then appeared in a mask and with her voice disguised and said, “I am so thrilled that my monster has made it this far. But, secretly, me and the babies do miss him.” She was referring to their fur babies. A calendar with August 2025 that said, “SUMMER BREAK” on it in big red letters was then shown. This was a reference to Brian’s 2023 song, “See You Next Summer.” Mad Scientist Monster’s wife continued, “He keeps us safe and sound and that’s important to me because, growing up, I didn’t have that.” A chess board with only knights was then shown. Florida Georgia Line has a song called “Bumpin’ the Night.“

Mad Scientist Monster’s wife shared, “I was orphaned when I was a teenager, and, with no family stability, I became my own parent and my own protector. When I met Mad Scientist Monster, I didn’t know how to be loved. Didn’t think I deserved it. But he was patient with me. He knew I was a little broken from my past, and wanted to help me rebuild, piece by piece.” Mad Scientist Monster was then shown hugging his wife. Brian and his wife have a very supportive relationship.

Mad Scientist Monster’s wife went on to say, “So I helped him too. I was an audience of one while he worked on his first huge single. And I’ve done everything I can to support his, well, our, dream. Honey, I came to life when you came into mine. Now go out there and share your talent with the world.” Brian and his wife are very much in love.

After Mad Scientist Monster’s performance, he shared, “I wanted to do ‘The Scientist’ because it’s a pretty emotional and heartfelt song, let’s be honest. Which is really different than what most people know me for. Party anthem kinda guy.” Florida Georgia Line is known for their party anthems such as “Cruise.” Their musical style is “bro-country,” which incorporates rock and hip-hop styles, and includes themes about partying and having a good time.

Mad Scientist Monster sang a crowd-pleasing version of “A Bar Song (Tipsy)” by Shaboozey, while Coral sang an emotional version of “What Was I Made For” by Billie Eilish. Mad Scientist Monster advanced directly to the finale, while Coral went to the Smackdown with Boogie Woogie.

After Coral called Mad Scientist Monster a “crazy old scientist” in her clue package, he said, “Hey, I’m not that old!” Brian is 39 years old. Mad Scientist Monster continued, “Plus, with age comes experience. And, believe me, I’ve been training for this my whole life. As an athlete-turned-singer I apply a sports-mentality to all my performances.” This was another reference to Brian being a baseball player before he was a singer.

Mad Scientist Monster then said, “I’m not just cruisin’ here,” which was a reference to Florida Georgia Line’s hit song, “Cruise.” He added, “I’m workin’ hard. Doing cardio, keepin’ my strength up, carbo-loading, so I’m more than ready to take down this little tadpole.” Mad Scientist Monster was then shown eating spaghetti. Mad Scientist Monster later added, “The probability of beating me is slim.”

After Mad Scientist Monster’s performance, he revealed that he has a connection to Robin. He explained, “Oh, Robin. Remember that Lucky Duck clue about someone stealing something from you? Well, that was me back in 2013.” 2013 was the year that Florida Georgia Line won the American Music Award for Single of the Year for “Cruise,” which won over Robin’s “Blurred Lines” with Pharrell Williams and T.I.

Mad Scientist Monster began his clue package by saying, “Let’s get this party started. Let’s go win this thing. You know, to be honest, this music thing was sort of a happy, crazy accident. I’d always thought I’d be an athlete. And, when that wasn’t the case, I was lost. My dad was the one who motivated me. And he encouraged me to go the unconventional route. And, wow, am I glad I did.” This was another clue about Brian’s original plan to become a baseball player.

Mad Scientist Monster went on to say, “Watching him see my success with so much joy over the years is why I keep going. And, when my group parted ways, he’s the one who gave me the strength to know I could go out on my own. Being here has been a once-in-a-lifetime opportunity to reintroduce myself to the world. And the warm response has been validating and intoxicating. It’s made me think going solo is the right choice after all.” Brian went solo after Florida Georgia Line broke up.

Mad Scientist Monster concluded by saying, “Now, making it to the finale, I’m more encouraged than ever that I’m on the right path. I’ll always be grateful to Masked Singer for giving me this chance to shine on my own. Yep, I’d say, regardless, this grand experiment has been a success.”

After Mad Scientist Monster’s performance, he told Robin that he wasn’t giving back what he took from him, which puzzled Robin. Then, another clue was given about his identity, which was a phone call from his parents. His mom congratulated him for making it to the finale, and she said that they were so excited for him. His dad added that they were proud of him.

Mad Scientist Monster’s mom shared that they weren’t surprised because he’s competitive, and he worked really hard. His dad concluded by saying that he did a great job doing something totally different, and they wished him the best as he went forward. They wanted him to go ahead and knock this thing out of the park and win it. His dad added, “Love ya!”

Mad Scientist Monster said, “Aw! Thanks, Mom and Dad!” He shared, “Oh, my parents literally mean everything to me. I’m very blessed. They’ve been there every step of my life. And, I’m feeling the love up here. Very grateful for my parents.” Brian’s parents have always been very supportive of him.

After the audience and panelists voted, Brian placed fourth in The Masked Singer season 13 and his most meaningful clue from his Crack the Case Clue Case was revealed. It was a gold fish necklace. Mad Scientist Monster explained, “That’s a tarpon necklace. You know, it represents a lot to me: I love the outdoors. I grew up on and near the waters. And I love fishing with my dad still to this day.” The tarpon is from Florida, which is Brian’s home state.

As Mad Scientist Monster, Brian gave incredible performances during The Masked Singer season 13. He has a beautiful voice and star quality, so it was no surprise when he advanced to the finale. He concluded his run on the show with a triumphant unmasked of “A Bar Song (Tipsy).” Brian captivated everyone as Mad Scientist Monster, and he’ll be remembered on The Masked Singer forever.
