Sunday Rose Kidman Urban celebrated Halloween with a costume that paid homage to both her mother, Nicole Kidman, and the singer Adéla. The 18-year-old dressed as Adéla, referencing the singer's hit song "Nicole Kidman," which in turn draws inspiration from the actress's filmography.

Urban shared her Halloween look on Instagram, captioning it "Babygirl in control." This phrase serves as a dual nod to Adéla's song lyrics and the title of Kidman's recent steamy romance film, "Babygirl." The costume featured a pink wig, mimicking Adéla's signature hair color, and ballet shoes.

Fans reacted enthusiastically to the post, with many praising the "iconic" and "cheeky" tribute. Comments included expressions of excitement and appreciation for the layered references. One user noted, "She knew," while another anticipated the reveal.

Adéla's song "Nicole Kidman" features lyrics that touch upon Kidman's movie roles, including "Moulin Rouge!" and the sexually charged drama "Babygirl." The song's lyrics state, "Every single night, I pray that my t*ts are sittin' right. Moulin Rouge, my corset is so tight. Babygirl in control, I feel like Nicole."

Kidman herself has publicly expressed a mix of embarrassment and amusement upon hearing the song. She shared on "The Tonight Show Starring Jimmy Fallon" that she was surprised by the tribute and found Adéla's music video, which recreates looks from Kidman's films, to be "really good."

Kidman, who has given Adéla her blessing to use her name in the song, commented that the singer looked "even better" than she did in the original movie costumes. The singer reportedly sought permission from Kidman before releasing the track.

"Babygirl," the film referenced in Sunday Rose's costume, stars Kidman as a married executive who enters into an affair with a younger intern. The movie has been noted for its explicit scenes, with some audiences reportedly leaving theaters before its conclusion.
