Some celebs like Rihanna, Miley Cyrus and others make a point to refuse to be role models. Demi Lovato is taking those ladies to task. What did she say when press pointed out that other stars don't want to go the role model route?

"I used to say that too," Lovato confessed. "That was my excuse to do whatever the f--- I wanted and not give a s--- about what other people thought," she said. "Then I ended up going through some stuff. I realized I'm never going to escape the fact that I'm in the public eye, so I might as well do the best I can."

That "stuff" she went through was serious. Lovato admitted, "When I was in treatment, I honestly thought my career was over. "But when I came out of treatment, I had more supportive fans than ever."

Just how scary did her issues get? "I'm battling with internal thoughts on how honest I should be," Lovato said. "Yes, I've been very honest, but if people really knew how dark and deep my struggles got -- not just with my eating disorder but with drugs and alcohol -- they'd be really shocked. But I'll most likely end up saying everything. Maybe it'll help other people in the industry who are headed down the wrong path."
