Country star Joe Nichols is getting treatment for a longtime substance abuse problem. "As Joe has alluded to in interviews over the past year, he has struggled with the issue of substance abuse," a posting on his Web site by Nichols' management team reads. "In order to become a healthier person and deal with long standing issues, he has entered into a rehabilitation program for consultation and treatment."

This announcement comes just one month after Nichols married his girlfriend of 12 years. The couple honeymooned in Florida before the singer hit the road to promote his new album, 'Real Things.' He canceled a concert Saturday in Waco, Texas, so that he could begin his treatment.
