Demi Lovato has always been open about her issues, says TheWrap. In 2010 she checked into a rehabilitation center. She said it was to deal with an eating disorder, self-mutilation and other issues. Over the next eight years, she released multi-platinum songs and albums. Sometimes her lyrical content was about her battles with drugs and alcohol. On Tuesday, the 25-year-old was reportedly hospitalized for an overdose. A month earlier, she released a new song called "Sober," indicating she relapsed after six years of sobriety.
