The Sunday Rose Halloween costume was easy to miss unless you knew the reference. The 18-year-old model, daughter of Nicole Kidman and Keith Urban, shared photos on 1 November of herself in a pink wig and a ballet-inspired outfit, according to People. The look was a tribute to a singer who has built a hit around her mother’s name.
The Sunday Rose Halloween costume explained
People reports that the costume appeared to be a nod to Adéla, a 22-year-old Slovak singer best known for “Nicole Kidman”. The song is named after, and written about, the Moulin Rouge! star. Sunday Rose left a clue in her caption: “babygirl in control” is a lyric from the track.
Adéla first appeared on The Debut: Dream Academy, People notes. Her song has travelled far enough to reach its subject. Kidman was seen reacting when it was played at the 2026 Victoria’s Secret Fashion Show in October, according to the same report.
We covered the song’s rise in an earlier piece, Nicole Kidman Gets Her Own Pop Song and a Halloween Tribute.
What Adéla has said about Kidman
Adéla has been open about her surprise. On The Tonight Show Starring Jimmy Fallon, she called Kidman “my muse”. She said the actress knew the date of her New York show and “is doing charity work by mentioning my name all over the town”.
She also told Pop Crave, as quoted by Billboard and repeated by People: “I can’t believe Nicole Kidman knows who I am.” She added that it meant a lot to be recognised by the person she wrote about, calling Kidman “a legend”.
Sunday Rose on growing up with famous parents
The costume lands soon after Sunday Rose’s own press. In an interview with Vogue Germany published on 20 October, she said she’s “very aware” of the opportunities she’s been given and is “truly grateful” for them. She told the magazine she tries to arrive at every job with a positive attitude, however tired or jet-lagged, and to treat everyone with respect.
Asked whether she had ever deliberately kept her parents’ names to herself, she said not really. Few people live in the area where she grew up, she explained, so most people knew who her parents were by the time she started school. Our earlier coverage of that cover is here: Nicole Kidman’s Daughter Sunday Rose Fronts Vogue Germany.
Kidman’s own autumn look: denim on denim
Kidman herself has been in the style pages too. Yahoo Shopping reports that she recently posted an Instagram photo in a matching dark-wash denim jacket and wide-leg jeans from Khaite. She wore them over a black lace-trimmed top, with animal-print pumps, oversized sunglasses and a red rosette pin.
Yahoo’s writers call the matching-wash approach an easy transitional formula for autumn and early spring. The piece goes on to suggest high-street jackets from Old Navy, Levi’s, Gap and Quince as cheaper alternatives. That part is a shopping guide, not news about Kidman.

What happens next
Neither Kidman nor Urban has commented publicly on the costume, according to the sources we read. Adéla’s song remains the talking point, so expect more mentions as the pop star continues to promote it. You can follow everything we publish on the actress on our Nicole Kidman page.
