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

Naomi Watts and her youngest child Kai were two peas in a pod on Monday when they stepped out in stylish dresses at Dior’s pre-fall fashion show in Brooklyn.

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

The Australian actress, 55, opted for a plunging neckline and looked very chic in an all-white gown with ruffled sleeves and a long gold chain.

She enhanced her angelic look with a black designer handbag, a chunky black ring and sky-high heels with a gold sheen.

Meanwhile, Naomi’s teen Kai, 15, was proud of Dior as they stepped out in the $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 much the same way before highlighting their near-identical features with minimal makeup looks.

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

Despite her split from Liev, the former couple have remained friends and are committed to co-parenting their two children.

In June last year, Naomi married her partner Billy Crudup, 55, in a New York City courthouse.

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

The British-Australian star stunned in a white $7,400 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 resembled an engagement ring.

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

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