Country Singer Locked Back Down in Rehab

Keith Urban put himself into rehab on Thursday night, for his cocaine addiction. He not only has been known to be a cocaine addict but a sex offender as well.

His new wife, actress Nichole Kidman, was standing by her husband's side the entire time he was checking himself into rehab.

Urban supposedly apologized to her, saying he regrets hurting her, especially since she has been so supportive. The country star apparently confessed to Kidman of being in rehab before, for his cocaine abuse.

Urban started his music career in a group called "The Ranch," whose album was a complete disaster. The discouraged singer started drinking and using cocaine. In 1998, he checked into Cumberland Heights Treatment Center in Nashville Tennessee.

He was supposedly sober for eight years, however there is speculation now.

Urban also had the media stirring with rumors of him getting intoxicated at his bachelor's party and having sex with a porn star from the party. He denies all rumors about the incident.
