Kai shared some photos from the big moment on social media, captioning them with: "Omggg my heart is so full ilysm," and it's clear their famous parents were bursting with pride.

"Be still my beating heart!!" mom Naomi commented. "Bravo darling ILSM and what a show!!" with dad Liev adding: "Beyond beyond Kai." Top model and fellow A-list progeny Amelia Gray also wrote: "Yessssss," with stepmom Taylor also adding: "GO GIRL!!!!! YOU ARE MY HERO."

Naomi shared some photos from the big day on her own social media page and wrote: "That's my @maisonvalentino baby! I'm squealing with pride. Ilysm." Liev and Naomi also share son Sasha, 17, who is a budding actor and model.

Kai has become quite the döppelganger of the Mulholland Drive star, even sharing the same penchant for fashion, as the two have been photographed front row at fashion shows several times.

Most recently, Naomi shared a tender tribute to her youngest on their 16th birthday back in December, writing on Instagram alongside a pair of photos: "Darling Kai, Happy sweet sixteen."

"Your sweetness is pure and I'm the luckiest mommy in the world and that world is SO lucky that you are here!! You blow me away with your wild spirit, strength and yes your soft sweetness too. You even let me post a baby picture!! I thank my lucky stars I get to be your mom. I Love you to the moon."

During a previous conversation with Net-A-Porter, Naomi revealed that when it comes to acting, her two kids "got the bug," although was "definitely mixed" when it came to her own thoughts on the matter.

She was also full of praise for her ex, who now has a one-year-old daughter with his wife Taylor, and how they're able to find joy and ease in co-parenting together despite their split and new relationships (Naomi is married to actor Billy Crudup).

"We're doing things very differently," she remarked. "I'm pretty proud of us, corny as that may sound. We've made it our absolute priority to be good and kind to each other and we're absolutely committed to that."

Liev and Naomi are still very friendly, most recently getting the opportunity to interact with each other at the Critics Choice Awards, where the former won for his turn in The Perfect Couple (starring opposite his ex's best friend Nicole Kidman) and the latter was nominated for Feud. Both brought their son Sasha as a date.
