In his bid for stardom, the country pop star posed for the saucy adult magazine eight years ago.The fresher-faced Urban is pictured reclining on a couch wearing nothing but a guitar, looking sultry for the camera.
Kidman apparently has got hold of the revealing photographs only only recently and is said to have liked what she saw.
"Nicole was impressed with the shots," Urban told Britain's New! magazine. "It was spread over two pages and had staples in all the right places."
It is alleged Kidman tried to get her hands on the photos in 2005 after their first formal date in New York's Central Park.
Kidman had supposedly told a friend her now husband was "hot, hot, hot" and asked someone to track down the nude shots.
The couple have simmered things down and live in Nashville looking after their seven-month-old daughter, Sunday Rose. Although the 41-year-old country star enjoyed stripping for the publication, he said he was unsure if he would pose again because of his family commitments.
"I am a dad and a totally different person now," Urban said. "But I might consider it if my fans demanded it." It seems Kidman isn't adverse to flashing her flesh for a photo shoot either.She was said to be considering asking Parisian photographer Patrick Demarchelier to take exclusive shots of her pregnant body just before giving birth.
