Kidman desperate for baby

Nicole Kidman is desperate to have a baby before she is too old.

The 38-year-old actress is reportedly wants to conceive before she turns 39 next year and plans to accompany her new husband, country singer Keith Urban, as he tours the US.

In preparation for her stay, Keith has fitted the bus with a large double bed, a kitchenette and a comfortable seating area.

A source told Britain's Grazia magazine "The plan for now, while they are trying, is that Nicole and Keith should not spend a moment apart.

"Keith's going to be on the road at the start and end of the month and Nicole's coming along too. Partly it's because they are newly-wed and in love and because she has time on her schedule. But everyone also knows that they really want a baby, and you can't afford to be apart if you are trying."

The reason for the urgency is that Nicole is set to shoot a new film with 'Moulin Rouge' director Baz Luhrmann in eight months time.

Nicole - who has two adopted children, daughter Isabella and son Connor, from her marriage to Tom Cruise - is said to be concerned that by the time the movie wraps she will be 39 and her chances of having a baby will have decreased.

The source added: "She knows that the dream of having a baby is still just within her grasp as long as she seizes the moment. She wants it to happen now."
