Celebrity kids and their famous parents | In pictures: Drake’s son Adonis with his mother Sophie Brussaux

Selma Blair’s 13-year-old son is looking more and more like his famous mum as the years go on.

The Legally Blonde actress, 52, took to Instagram with a carousel of photos from a Californian holiday she is on with her son, Arthur.

The last photo in the carousel was a selfie of the actress and her teenage son appearing to enjoy a day out together on the water.

As he smiled for the camera, young Arthur shared an uncanny likeness to his mum and looks all the more grown up sporting a new buzz cut.

Blair took to the caption to write: “I am having the most gorgeous days and nights with with My son and love.”

Blair shares Arthur with her ex Jason Bleick. Despite being separated, the actress explained to People that the pair share an amicable co-parenting relationship.

“Jason is a huge part of Arthur’s life. He’s shown up in a big way,” she said.

“I’m really proud of us.”
