Demi Lovato's 'Skyscraper' inspiration

Demi Lovato's 'Skyscraper' was inspired by all of the people who didn't stand by her when she went to rehab.

The singer and actress was admitted to a facility last November for three months to receive treatment for her eating disorders and self-harming and although she had incredible support from her family and close friends, Demi admitted there were many 'artificial' pals who ignored her when she needed them most.

She explained: 'It's to every person who tried to bring me down. Everyone has the bully or the mean girl or the ex-boyfriend who tried to bring them down. For me, I think of the people who really weren't there for me when I went into treatment. It was a really dark time for me because I had only a few people - I had surrounded myself with so many artificial friendships. It's about those people too.'

Demi, 19, has previously dated Joe Jonas and has reportedly rekindled her relationship with her 31-year-old former boyfriend Wilmer Valderrama, but says anyone who wants to be her boyfriend will have to be prepared to deal with her emotional baggage.

She told US Glamour magazine: ' someone who's not only supportive in my career, but also in my emotional recovery. It's a big responsibility dating me. Because I come with a little bit of baggage, you know? I'm completely open. I'm honest about the journey I've been on, so I definitely don't take dating lightly anymore. And they have to make me laugh!
