Keith Urban says wife Nicole Kidman is a 'maniac in bed'

Keith Urban has gotten pretty candid about his personal life with Nicole Kidman.

The 51-year-old country star has admitted a rather racy lyric on his latest album, Graffiti U, is about his wife.

In the song ‘Gemini’ Keith sings, “She’s a maniac in the bed, but a brainiac in her head.”

Well, it turns out Keith is specifically referring to Nicole, and she apparently totally digs it.

“The song is actually about Nicole – and she loves it,” the Aussie songwriter recently told iNews.

It was with the help of fellow singer-songwriter Julia Michaels, that the interesting and revealing lyric was born.

“It’s a fun song. My co-writer Julia Michaels asked me to describe Nicole and that’s what came out,” Keith explained. “She is Gemini, but she’s not a contradiction.

“She can roll with things.”

The star sign certainly fits the bill as Nicole’s birthday falls on June 20, which makes the 51-year-old a Gemini.

Keith and Nicole have been married for nearly 13 years, and have two children together, 10-year-old Sunday Rose and eight-year-old Faith Margaret.
