Naomi Watts’ youngest child Kai stuns alongside the actress as they attend New York Fashion Week

Naomi Watts put on a stylish performance when she attended New York Fashion Week with her youngest child Kai on Saturday.

The Australian actress, 55, dressed to impress in a long white dress and black coat as she left the Khaite fashion show with the teenager.

The Hollywood star completed her stylish look with a pair of black gloves and black shoes.

Naomi left her short blonde locks out and showed off her flawless complexion with a natural makeup palette.

She was joined by Kai, 15, who wore a long brown dress and a leather jacket with a fur collar as she posed with the actress.

Naomi shares her two children (Alexander (16) and Samuel – who prefers the name Kai (15)) with her ex-partner Liev Schreiber, with whom she broke up after 11 years in 2016.

Despite her split from ex-partner Liev, the former couple have remained on friendly terms and are committed to co-parenting their two children.

In June, Naomi tied the knot with her partner Billy Crudup (55) at a courthouse in New York.

Naomi shared news of her marriage with her followers as she posted a photo on Instagram of herself and her new husband posing on the steps of the Manhattan courthouse shortly after tying the knot.

The British-Australian actress stunned in a $7,400 white Oscar de la Renta Sweetheart Water Lilly Guipure dress as she captioned the post: ‘Hitched.’

Naomi first sparked rumors that she and Billy were engaged earlier in the year when she sported an enormous marquise diamond, along with a diamond-encrusted band.

However, the star refused to confirm the engagement chatter, even after American Today show host Hoda Kotb directly referenced it during a late April appearance on the morning talk show.

Towards the end of Naomi’s segment, Hoda joked that her ‘eye hurts’ from the ‘big glitter coming from some ring over here.’

Naomi and Billy met on the set of her 2017 Netflix series Gypsy, in which she starred as a therapist who uses an alias to develop close (and unethical) relationships with people intimately connected to her patients, while Crudup played her husband.

The costars later began dating in 2017, a year after Naomi split from her partner of 11 years, actor Liev Schreiber.
