Actress Nicole Kidman, 39, and her husband of four months, country singer Keith Urban, took a stroll outside of the Betty Ford Center in Palm Springs on November 12.

Nicole Kidman is reportedly pregnant.

The Moulin Rouge actress allegedly broke the happy news to her country singer husband Keith Urban when she visited him at a California rehabilitation clinic, where he is being treated for alcoholism.

According to reports, Nicole - who has two adopted children with ex-husband Tom Cruise, Isabella, 13, and 11-year-old Conor - took two home pregnancy tests to be doubly sure before making the trip to the Betty Ford Clinic on October 29.

A source told the National Enquirer magazine: "Keith was happy, but uneasy, about the news. He knows how desperate Nicole has been to have a baby, but the timing couldn't be worse for him."

Despite Keith's reservations, the pair - who married in Australia four months ago - looked very much in love as they strolled round the gardens of the clinic hand-in-hand and canoodled on a bench.

Nicole, 39, was by her Grammy award-winning husband's side when he voluntarily enrolled himself on the 30-day rehab programme on October 19.

At the time, Keith - who has previously admitted to a cocaine addiction - released a statement, saying: "I deeply regret the hurt this has caused Nicole and the ones that love and support me.

"One can never let one's guard down on recovery, and I'm afraid that I have."
