Naomi Watts Shares Sweet Photo with Lookalike Daughter Kai on Her 16th Birthday: ‘Luckiest Mommy in the World’

Naomi Watts’ daughter is celebrating her sweet 16.

Over the weekend, the actress, 56, shared a few photos on her Instagram as she celebrated her daughter Kai on her 16th birthday. In one photo, the lookalike mother-daughter duo poses together, with Watts in an off-the-shoulder white dress and Kai in a black halter-top dress.

Watts also shared a sweet throwback photo of Kai as a baby, wearing a blue shirt and posing amid tree branches.

“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!!” the proud mom wrote in her caption.

“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 🌙 💕.”

The actress shares Kai and her son Sasha, 17, with ex Liev Schreiber.

“Love you Kai Kai,” Schreiber sweetly added in the comments.

Over the summer, Watts shared a fun video on her Instagram Stories of her daughter Kai performing an impromptu dance with a friend to some beautiful live music in Paris.

In the video, Watts, who appeared to be filming, walked through the French capital at night, and captured a street musician playing the violin amid the old buildings. She then panned the camera to show Kai and a friend. The teen — who wore a black cropped t-shirt, blue jeans and sneakers — and a pal held each other’s arms as they spun around in a circle while the musician played.

Watts then turned the camera back to the violinist as she walked past him, and then back to Kai who was jogging, apparently to catch up with the group, as they approached an archway.

“Evenings in Paris,” Watts captioned the atmospheric video.

In April, Watts brought Kai along with her as she attended the Dior pre-fall show at the Brooklyn Museum in Brooklyn, New York.

Wearing a long white dress, the proud mom held hands with Kai, who wore a white pleated skirt printed with red flowers and butterflies along with a matching sweater.

Both Watts and Kai wore their matching blonde hair down and straight, sitting next to each other as they sat front row for the event.
