Demi Lovato Still Struggles With Bulimia, Cutting Post-Treatment

Demi Lovato is continuing to open up about her road to recovery, and this time, it's not via Twitter or during an intimate interview.

In her MTV documentary special, Stay Strong: Demi Lovato, the 19-year-old star sat in front of a studio audience while answering host SuChin Pak's questions about her longtime battle with an eating disorder and cutting.

"I cannot tell you that I have not thrown up since treatment," the "Skyscraper" singer told Pak during Tuesday's airing. "I can not tell you that I have not cut myself since treatment. I'm not perfect. This is a daily battle that I will face the rest of my life."

Lovato checked into rehab facility Timberline Knolls in November 2010, where she stayed three months to treat emotional and physical issues. The treatment center has since remained a big part of her life — during the documentary, she revisited the Illinois-based center to share her story and words of encouragement with patients there.

"I just remember being 12, 13 and going through these issues alone," she told Pak. "I didn't really have a celebrity or anybody in the public eye to look at and say well, 'if she got through this, then so can I.' I'm not fixed. This is a daily battle. But I continue to work my butt of because now I wanna be a legitimate role model."
