Actress Nicole Kidman has credited husband Keith Urban with giving her a true purpose in life. The 40-year-old Moulin Rouge! star says she turned to acting to battle her feelings of depression - but only felt fulfilled when she met the country music star. She says, "Actually, I'm not that interested in working right now. I think that a lot of my wish to work was about wanting to get lost, not wanting to be in the world. "I have a reason to be in the world now and that reason is Keith."
