If you’ve been wondering about the identity of the woman Keith Urban describes as a “maniac in the bed” in his song “Gemini,” you can rest easy now. The country singer confirmed that he is, of course, talking about his famous wife, Nicole Kidman.

“The song is actually about Nicole — and she loves it,” Keith revealed to iNews in a new interview, giving the 51-year-old Oscar-winning actress credit for inspiring the sexy lyric as well as another one that calls her “a brainiac in her head.”

Keith, also 51, added: “It’s a fun song. My co-writer Julia Michaels asked me to describe Nicole and that’s what came out.”

“Gemini,” off Keith’s tenth studio album from last year titled Graffiti U, has had fans speculating for nearly a year. This tidbit gives them some insight into what may be happening when the Australian lovebirds are in private.

What should have tipped us off, though, is that Nicole’s zodiac sign actually matches the song title. Keith, for the record, is a Scorpio.

The couple, who have been married since 2006, share two children together, daughters Sunday, 10, and Faith, 8. Outside of her kids with Keith, Nicole also has two children, Isabella, 26, and Connor, 24, whom she adopted with ex-husband Tom Cruise. But if she could have it her way, Nicole would have 10 children with Keith.

Even though Keith thought the Big Little Lies star was out of his league when they first met, Nicole doesn’t see it like that and once recalled the moment it dawned on her that she wanted to marry him. All these years later, they still seem happier than ever.

This isn’t the first time Nicole has inspired Keith, the reigning CMA Entertainer of the Year, musically — and we hope it won’t be the last.

Oh, and while they’re at it, more karaoke sessions in the car, please.
