Troubled rapper Earl "DMX" Simmons has reportedly admitted to using illegal drug and was placed behind bars yesterday (March 10).

"He admitted to using cocaine, so he's back in our jail," said Maricopa County Sheriff Joe Arpaio. "I think it's about time to give him hard time." The get-tough sheriff said if the rapper is serious about kicking his drug habit, the Arizona jail system -- where X has already logged time on animal cruelty and drug possession charges -- could help him get clean. "We do have a great drug prevention program in the jail, so if he stays in our jail system I will consider (letting) him go through our program," Arpaio said. (MTV)

Simmons was arrested Tuesday by Adult Probation officers and charged with five counts of probation violation.
