Naomi Watts and Liev Schreiber are celebrating a milestone for their youngest.
The former couple recently celebrated their 16-year-old Kai making her fashion week debut during Valentino’s March 9 exhibition at Paris Fashion Week.
“That’s my @maisonvalentino baby!” Naomi—who also shares 17-year-old son Sasha with Liev—gushed in a March 9 Instagram post, alongside photos and videos of Kai. “I’m squealing with pride.”
Meanwhile, Liev—who also shares daughter Hazel, 18 months, with wife Taylor Neisen—couldn’t contain his delight over the occasion, also sharing his own post of Kai.
Alongside a photo of his daughter walking the runway, he wrote, “Ladies and gentlemen the one, the only, the indomitable @kaishreiberr!”
And of course, Kai also reflected on the meaningful moment.
“Omgg my heart is so full,” the 16-year-old wrote in a March 9 Instagram post, before adding to Valentino, its creative director Alessandro Michele and her glam team, “ilysm.”
Naturally, Naomi—who married Billy Crudup in 2023— had to heap more praise over her daughter, writing in a comment, “Be still my beating heart!! bravo darling ILSM and what a show!!”
While her appearance in Paris was her first walk across the runway, Kai has expressed interest in the fashion world before. After all, she was spotted attending a Dior pre-fall fashion show alongside her mom in New York last year, sporting a stylish red and white floral print skirt and a matching sweater.
As Kai steps into the limelight with her modeling career, the Mulholland Drive actress has previously expressed awe in how her daughter is maturing.
“Your sweetness is pure and I’m the luckiest mommy in the world and that world is SO lucky that you are here!!” Naomi wrote in a birthday tribute to Kai in December. “You blow me away with your wild spirit, strength and yes your soft sweetness too. I thank my lucky stars I get to be your mom. I Love you to the moon.”
