(Cover) - EN Showbiz - Demi Lovato advises people to "fake it till [they] make it".

The American songstress recently released her third studio album Unbroken. She began working on the record in July 2010, prior to entering a rehab facility for "emotional and physical issues".

Demi has battled with her demons, and now feels in a much happier place.

"The best piece of advice is to fake it till you make it," she told MTV News.

"When I first went into treatment, I didn't want to be there, and I was kind of like, 'I'll just fake it until I make it.' I stayed in there, and I started believing that I was in there for the right reasons. And even though I didn't want to be there at the time, some girls might not want to get help, but if they fake it till they make it, hopefully they can get the help that they need, and they can start to believe it, and they can actually see one day that it's actually the right thing that they're doing."

Demi has spoken candidly about her problems since leaving the treatment centre in January. The star takes being a role model for other young girls very seriously.

"I do feel a responsibility, but it's not a burden to me. I feel like there are certain choices in my life that I am faced with every single day, and I think, well, 'How would my little sister feel if I would do this? And how would she feel about this?'" she explained.

"I have days where I'm cranky, but I definitely want to be there for my fans and step outside and shake their hands and be there for them too, because I'm now a role model, and I want to be there for them." (C) Cover Media
