Naomi Watts and her youngest child Kai, 15, look the spitting image of each other as they step out in glamorous gowns during the Dior fashion show

Naomi Watts and her youngest child Kai were two peas in a pod on Monday as they stepped out in stylish dresses for Dior ahead of the fall fashion show in Brooklyn.

The mother-daughter duo looked radiant in ankle-length dresses, which featured flowing skirts and designer accessories, as they caught up with friends.

Opting for a plunging neckline, the Australian actress, 55, looked very chic in an all-white dress with ruffled sleeves as she accessorized with a long gold necklace.

She elevated her angelic look with a black designer handbag, a chunky black ring and towering heels, which boasted a gold leather.

Meanwhile, Naomi’s teenager Kai, 15, who was born Samuel, did Dior proud as he stepped out in the brand’s $4,900 red and white floral pleated skirt.

Kai paired it with the matching embroidered sweater, worth $4,500, from the same fashion label and accessorized with simple black pumps and a handbag.

Naomi and Kai styled their blonde locks in pretty much the same way before highlighting their almost identical features with minimal makeup looks.

Naomi shares her two children, Alexander, 16, and Kai, with ex-partner Liev Schreiber, from whom she split in 2016 after 11 years together.

Despite her breakup with Liev, the former couple have remained on friendly terms and are committed to co-parenting their two children.

Last June, Naomi tied the knot with her partner Billy Crudup, 55, at a New York courthouse.

She shared news of her marriage on Instagram, posting a photo of the lovebirds as they posed on the steps of the Manhattan courthouse shortly after tying the knot.

The British-Australian star 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 this year when she debuted a huge diamond that appeared to be an engagement ring.

Naomi and Billy began their relationship in 2017, a year after her split from Liev, just months after they met on the set of her Netflix series Gypsy.

In it, Billy starred as Naomi’s husband as she played a therapist who uses an alias to develop close and unethical relationships with people connected to her patients.
