Naomi Watts has shared an adorable 16th birthday tribute to her lookalike youngest child Kai.
The British-n actress, 56, took to Instagram on Saturday to share some heartfelt words alongside a sweet photograph of herself and Kai.
In the picture, Naomi looked every inch the doting mother as she beamed with pride at Kai while they held hands, both looking glammed-up for a lavish event.
The King Kong star cut a glamorous figure in an off-the-shoulder white gown while Kai looked every inch Naomi’s lookalike in a black halter-neck dress.
The King Kong star also shared an adorable photograph of Kai as baby and gushed over her youngest child in a heartwarming caption.
She penned: ‘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!!

Naomi shares Kai and her son Sasha, 17, with her ex, American actor Liev Schreiber, who she was in a relationship with for 11 years before they amicably split in 2016.
Liev has since married Taylor Neisen while Naomi went on to find love again with Billy Crudup.
Naomi and American actor Billy tied the knot in a modest wedding ceremony at a New York courthouse in June 2023.
They then exchanged vows for a second time a year later in a larger ceremony with their family and friends in Mexico.
Videos shared on social media by Naomi’s brother Ben at the time gave an insight into the lavish ceremony, with notable guests including Nicole Kidman and Isla Fisher.
Naomi’s child Kai and her niece Ruby were bridesmaids, and also in the wedding party were Naomi’s son Sasha and Billy’s son William, 20, who he shares with Mary Louise Parker.

In October, Naomi gave a rare insight into her relationship with Billy as she revealed the unique way they had celebrated her 56th birthday.
She shared a loved-up snap of herself and Billy together and told how they had spent her birthday playing pickleball – a competitive paddle sport similar to tennis.
She shared in a caption: ‘Thank you for all my lovely birthday wishes. Pickle ball with the hubster followed by a couples massage made it one of my all time favourites.’
‘See the bliss in my eyes. Grateful beyond words and for all of you too.’
Naomi and Billy met on the set of 2017 Netflix series Gypsy, in which she starred as a therapist who uses an alias to develop close relationships with people intimately connected to her patients, while Billy played her husband.
The co-stars began a relationship later in 2017, a year after Naomi had split from Liev.
