KEITH URBAN

Less than four months after marrying Nicole Kidman, Urban entered rehab for alcohol abuse in October 2006, checking out in January 2007. In an interview a month later, the country star thanked his wife, explaining, "They say grief makes hearts and closer bonds than joy ever can. We've been through a lot, and she's been extraordinary."
