Naomi shares Kai and her son Sasha, 17, with her ex, American actor Liev Schreiber, who she dated for 11 years before they amicably split in 2016.
Liev has since married Taylor Neisen, while Naomi found love again with Billy Crudup.
Naomi and American actor Billy got married in June 2023 in a modest wedding ceremony at a New York courthouse.
A year later, they exchanged vows for a second time at a larger ceremony with their family and friends in Mexico.
Videos shared on social media by Naomi’s brother Ben at the time gave insight into the lavish ceremony, which featured notable guests including Nicole Kidman and Isla Fisher.
Naomi’s child Kai and her niece Ruby were bridesmaids, and also in the wedding party was 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 when she revealed the unique way they celebrated her 56th birthday.
She shared a loved-up photo of herself and Billy together and talked about how they spent her birthday playing pickleball – a competitive paddle sport similar to tennis.
She shared in a caption, “Thank you for all my beautiful birthday wishes. Pickle ball with the hubster followed by a couples massage made it one of my all time favorites.”
‘See the bliss in my eyes. Incomprehensibly grateful and also for all of you.’
Naomi and Billy met on the set of the 2017 Netflix series Gypsy, in which she starred as a therapist who uses an alias to build close relationships with people closely connected to her patients, while Billy played her husband .
The co-stars started dating later in 2017, a year after Naomi split from Liev.
