The Oscar-winning actress walked the red carpet alongside her 17-year-old daughter, Sunday Rose Kidman-Urban, marking the teenager’s first-ever appearance at fashion’s biggest night.

A Glamorous Mother-Daughter Moment

Kidman, 58, stunned in a deep red sequined Chanel gown fresh from the brand’s 2027 Cruise collection, complete with a feathered peplum and flowing train.

Meanwhile, Sunday embraced spring in a soft pink and lilac strapless gown, pairing the look with a matching purse and statement earrings — instantly turning heads on the carpet.

The duo’s coordinated glam, styled by celebrity hairstylist Adir Abergel, added to the buzz, with Kidman opting for a sleek bang look while Sunday wore her hair long and side-parted.

Breaking the Met Gala Rule?

Sunday’s appearance has sparked debate — because the Met Gala has a well-known 18+ age restriction.

The rule, confirmed by organizers in previous years, states the event is “not appropriate for people under 18.”

That’s why fans were quick to notice the apparent exception, especially with Kidman serving as one of this year’s co-chairs alongside Beyoncé, Venus Williams, and Anna Wintour.

The 17-year-old has already stepped into the fashion world, making her runway debut with Miu Miu in 2024 and becoming a regular face during Fashion Week.

She has also spoken about how growing up around her mother’s film sets inspired her creative ambitions.

“My mum is someone who has always been so creative and my biggest inspiration,” she previously shared.

A Big Night for Kidman

This year’s gala is especially significant for Kidman, who is serving as a co-chair for the 2026 event themed “Fashion is Art”, celebrating the opening of the Costume Institute’s new permanent galleries.

Her appearance — and unexpected plus-one — quickly became one of the most talked-about moments of the night.
