Another day, another famous child hitting the runway.

There’s been quite a lot to take in at Paris Fashion Week, from the starry front-row appearances, to highly-anticipated designer debuts, and bubbling trends. However, a big portion of the week has been defined by sightings of famous offspring. From Lila Moss walking at Coperni to Paris Jackson stepping out in a totally sheer look for Stella McCartney and the Beckham kids sitting front row to support their mom’s latest collection—these past few days have been all about the celebrity kids. And on Sunday, that trend continued when Naomi Watts and Liev Schreiber’s daughter, Kai Schreiber, made her runway debut at the Valentino show.

Inside the all-red, bathroom-inspired venue, the 16-year-old took her first stroll down the catwalk in a leopard-print minidress that featured a feather-covered collar with bright purple dye decorating the middle.

For the rest of her look, Kai sported a pair of white tights with floral lacy embellishments, while throwing on a nude head cap and chunky black sunglasses with bright blue frames. Down low, she rocked a pair of white peep-toe heels that included floral accoutrements attached to the ankle straps.

It was clear Kai couldn’t have been more excited, as evidenced by the Instagram post she shared immediately following the show. “Omggg my heart is so full 💗,” she wrote in the caption. “ilysm @alessandro_michele @maisonvalentino @yad1m @paulhanlonhair.”

Meanwhile, Kai’s parents showed their excitement too, with Watts commenting: “Be still my beating heart!! 🙌♥️🙌 bravo darling ILSM and what a show!! @maisonvalentino 💥💪.” On his own account, Schreiber shared a runway shot of Kai, writing, “Ladies and gentlemen the one, the only, the indomitable @kaischreiberr!”

The newly-minted model is the youngest child between Watts and Schreiber, who were together from 2005 until their separation in 2016. They also share a son, Sasha, 17.

Both Kai and Sasha have taken an interest in the entertainment world, which isn’t wholly surprising given the careers of their parents. Most notably, the siblings provided voice work as the Young Wolf for the 2016 live-action remake of The Jungle Book. But if this runway debut is any indication, Kai may end up having a bright future as a model, too.
