1. Keith and Nicole sort of saved each other.

Keith Urban has often talked about how his love with Nicole Kidman might have saved his life. Soon after getting married, he entered rehab and emerged a better -- and happier -- man. Recently, Kidman returned the compliment, saying that she didn't think she'd ever find true love again after her divorce from Tom Cruise. "I never, ever take Keith or our love for granted and I always keep in my mind that my dream is to grow very old with him," Kidman tells Who.

The actress says she was in a lonely place prior to meeting Urban at 'G'Day L.A.' After a few dates, she found herself willing to open her heart to him.
