They're known for their public displays of affection and Nicole Kidman and Keith Urban's steamy bedroom secrets have been revealed!
Keith sings about his 12 year marriage to Nicole in his new single Gemini where he says his wife is "a maniac in the bed but a brainiac in the head."
He then says she "will wake you to make love in the middle of the night."
According to Life & Style, when Keith told Nicole that he was writing a song about their sex life 'it did not go down well at all.'
"Nicole's a very private person and theirs a song all about how wild she is in bed playing on the radio!" a source told the publication.
"But she's gone from feeling flustered to flattered. She loves it!" says Keith.
