Selma Blair and Kacper Sobieskiher teenage son Arthur Saint Bleick will have you seeing double.

The mother-son duo were adorably twinning at the Chloé Womenswear Spring-Summer 2025 show as part of Paris Fashion Week.

At the event, Selma, 52, donned a black ‘fit, including a sleek jacket over a sheer white, ruffled shirt and velvet, calf-length pants with merlot-colored knee-high boots. 

For his part, Arthur, 13, complemented his mother’s look by sporting a white T-shirt emblazoned with the Chloé logo, baggy black pants and white-and-black sneakers. Arthur also matched Selma’s signature bleach-blonde hairdo, proving the apple doesn’t fall far from the tree.

And Selma—who shares Arthur with her ex, fashion designer Jason Bleick—thinks her mini-me may be growing up a little too fast.

“I'm a grandma,” she told People on Sept. 6. "He's 13 and you would think he's 17. And he is the child that I will have to learn to keep a closer eye on. Because I love him very much."

And the Legally Blonde star—who was diagnosed with multiple sclerosis in 2018—shares more than just her love for fashion with her son: They also share a close bond.

"I love that she's so kind and liking,” Arthur said in an April 2021 Instagram video. “Not loving, liking."

And his mom feels the same way about him.

“I love that Arthur is so honest and playful,” Selma responded in the video. “And really bright. A really great companion. There’s nowhere that I’d rather be [than] next to Arthur… When he’s sleeping ‘cause when you’re sleeping you’re so loving.”

The Cruel Intentions actress added that her love for Arthur is easy.

“What’s my favorite thing? I just like him,” Selma added. “I like him a lot.”
