Jo Dee Messina will outline her struggle with alcohol abuse in her upcoming book, That’s Right, I’m an Addict. Messina recently completed treatment at a Utah rehabilitation clinic. She sought treatment after her manager confronted her about forgetting the words to one of her biggest hits — “Stand Beside Me” — at an event following the Super Bowl in Houston. On this week’s CMT Insider, Messina talks about her addiction and performs “My Way Home,” a song she wrote while in rehab. The episode of CMT Insider featuring Messina debuts Friday (May 7) at 7:30 p.m. ET/PT.
