Lovato, the former star of Disney Channel's "Sonny with a Chance", suffered an emotional breakdown in November 2010 when she pulled out of a concert tour with the Jonas Brothers and entered a three-month treatment program. She has since spoken openly about her 10-year battle with eating disorders and said she started cutting herself at the age of 11.

Lovato has since quit the TV series that made her one of Disney Channel's biggest international teen stars, saying she wanted to focus on her music career. Lovato has performed recently in New York and Los Angeles to promote the September release of "Unbroken." The new mini-tour will start in Detroit on Nov. 16 and end in Chicago on Dec. 3.
