Inspirational singer and actress Demi Lovato has admitted that when she first entered rehab she was so desperate to be released that she decided to "fake" getting better in order to decrease her time there. 

Speaking to MTV News, the 'Skyscraper' hitmaker explained that originally she didn't want to spend her time in the treatment centre and thought it would be easier to pretend she was fine so that she could get through the program as quickly as possible:

"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."

She also added that she is proud to be a role model after going public with her emotional and physical issues, which included an eating disorder and coming to terms with being bipolar, and said she now feels a need to "be there for my fans":

"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.

"I would say: Speak up, and don't be afraid to get help, because it could save their lives."
