NICOLE KIDMAN

After ducking and dodging baby rumors for months, the actress – who checked out an art gallery in Sydney with husband Keith Urban on Jan. 4 – finally revealed her big news three days later. This will be the first child for the couple, who wed in June 2006 (Nicole also has two children with Tom Cruise, Isabella, 15, and Conner, 12).
