Nicole Kidman 'expecting a baby'

Nicole Kidman and her husband Keith Urban are expecting a baby, according to a report in the Daily Mail today.

The newspaper claims that Kidman and Urban shared the news with their families during the Christmas holidays.

Kidman already has two children, Isabella, 14, and Conor, 12, who she adopted when she was married to Tom Cruise. The baby would be the actress's first natural child.

Nicole recently revealed that she was planning to take a break from movies in 2008, because she wished to go on tour with country singer Urban.

The couple tied the knot in Sydney, Australia, in June last year.
