Nicole Kidman and daughter Sunday Rose, 15, rock similar black outfits at Paris Fashion Week

Nicole Kidman took her teenage daughter as her plus-one to Paris Fashion Week and both have never looked so stylish.

It was a family affair for besties Nicole Kidman and Naomi Watts at Paris Fashion Week.

The Aussie actresses chose to bring their children with them as their dates to Balenciaga’s Haute Couture fall/winter show on June 26.

The Big Little Lies star, 57, was twinning with 15-year-old Sunday Rose Urban, with mother and daughter both wearing similar black dresses and dark sunglasses.

Kidman rocked a fitted, floor-length high-neck dress, while Sunday – who she shares with her singer husband, Keith Urban – opted for a similar velvet body-con mini-dress that had a similar turtleneck design.

They both also wore their long blonde hair down and super-straight as they took their spot front row at the event.

Meanwhile, Watts, 55, arrived with her youngest child Kai Schreiber for the rare public outing.

The Feud: Capote Vs. The Swans actress and Kai, 15, co-ordinated for their stylish day out, wearing complementary black and white outfits and matching black sunglasses.

Watts – who also shares son Sasha, 16, with ex-husband Liev Schreiber – wore an edgy white blazer complete with a deep V neckline collar design and pencil skirt, while Kai went the opposite in a black pencil skirt and sheer black lace blouse over a bralette.

Kidman and Sunday and Watts and Kai were all later seen sitting next to each other in the front row.

In April, Kidman made some gushing comments about her daughters, who she credits for her success. The Aussie actress also shares daughter Faith with Urban.

“I have my sister, mother, nieces, nephews, daughters. I’m raising a soon to be 16-year-old and a 13-year-old who are divine,” she told People.

Kidman also cosied up to Katy Perry at the event.

“They’re just lovely people and I’m so lucky that I have Keith, who’s just my love, my deep, deep love. That gives me the ability to go and do whatever I have to do because I know where I can come back to.”

Watts is just as enamoured with her children. Last year, for Kai’s 14th birthday, the actress got emotional as she marked the special day in an Instagram tribute.

“You are everything to me. I’m so lucky to be your mum,” she wrote at the time.

“Keep dancing and showing the world your dynamic and glorious spirit.”
