Nicole Kidman is pregnant, it has been claimed.

'The Golden Compass' star and her country singer husband Keith Urban reportedly told their families over Christmas that they are expecting their first child together, according to Britain's Sunday Mirror newspaper.

Former cocaine addict Keith, 40, checked into rehab just four months after their marriage in June 2006 to be treated for alcoholism.

Nicole, 40, admitted to Weekend magazine: "They say the first year of marriage is the hardest. Well, it's 18 months now and everything is fine. Please God it will stay that way.

"I turn down films because I don't want to be apart from him. It's a wife's place to be at her husband's side, after all.

"So I go on tour with him when he is performing and I sit in the dressing room and sew buttons on and make his tea. Afterwards we go back to the hotel room, switch on the television and fall asleep on the sofa.

"He says I am the most important person in his life, and he is certainly the most important person in mine.

"My dream is that we live a long life and become old people together."

The Oscar winning actress is due to start filming 'The Reader' with Ralph Fiennes next month, but has spoken of "winding down" her career to focus on family life.

A representative for Nicole said yesterday (29.12.07): "She is not pregnant. As far as we're concerned it is another rumour."
