This Aussie actress first caught our attention in 1990, playing Tom Cruise's character's love interest in Days of Thunder. Not only did she go on to marry her leading man, but she finished up the 1990s by earning critics' praise for her roles in Billy Bathgate and To Die For. In 2001, shortly after her marriage to Tom Cruise ended, Kidman made a triumphant turn in Baz Luhrmann's romantic musical Moulin Rouge!. A string of box office- and critical-successes followed, including The Others, The Hours and Cold Mountain. In 2006, she married musician Keith Urban. The couple welcomed daughter Sunday Rose to the world in 2008, and in early 2011, their daughter Faith was born.
