Keith Urban Checks Into Rehab

Country star Keith Urban voluntarily checked himself into a rehab facility Thursday night with wife Nicole Kidman by his side.

"I deeply regret the hurt this has caused Nicole and the ones that love and support me," Urban said in a statement. "One can never let ones guard down on recovery and I'm afraid that I have. With the strength and unwavering support I am blessed to have from my wife, family and friends, I am determined and resolved to a positive outcome."

It is not known what type of addiction for which Urban is seeking treatment. However, the singer has previously acknowledged overcoming a cocaine addiction.

Urban has been forced to cancel all promotions for his latest album, 'Love, Pain and the Whole Crazy Thing.'
