Selma Blair takes look-alike son Arthur as her front row date to Paris Fashion Week

Bonjour, Arthur.

Selma Blair made an appearance at Paris Fashion Week with a special guest by her side: her 13-year-old son, Arthur Saint Bleick, whom she shares with ex Jason Bleick.

The pair sat front row at the Chloé fashion show on Thursday with the teenager and the “Cruel Intentions” actress looking like twins with platinum blond hair.

Blair, 52, wore a scalloped-edge black cardigan over a white ruffle shirt, paired with a black skirt and knee-high boots while Arthur chose a T-shirt with the brand’s name splashed across the front and black pants with sneakers.

This marks the first runway show for Arthur — and his first trip to Paris, according to Blair’s Instagram.

“I love you my darling boy. My devilish Saint. Your first time in Paris should always be with someone who loves you the most,” she captioned a selfie in bed with Arthur. “So here we are. I’m so grateful. I couldn’t be happier. Goodnight. Sweet dreams.”

And he’s certainly turning into a clotheshorse, with Blair revealing earlier this year that she shares designer clothes with her teen.

“I love a little vintage Chanel jacket with denim shorts and a pair of my son’s sneakers. I love nothing more than to look like a f–ked-up debutante,” Blair told Us Weekly in July.

When asked if she actually swapped clothing with the tween, the star replied, “Yes! There was a point when I was buying a lot of Balenciaga because he wanted it.”

Arthur was also inspired by his mother when he buzzed his hair off and bleached it blond last month, with the duo posing for a mirror selfie on Instagram to show off the big reveal.

He wore his hair in a longer two-toned style earlier this summer, with the actress sharing in June, “Arthur Saint ! I love these boys. Arthur is my height now , with a bleached half a head, reminiscent of a New York black and white cookie.”

We expect to see more of Arthur in the fashion world soon enough.
