Demi Lovato: Q102 Jingle Ball QT!

Demi Lovato razzles and dazzles at the 2011 Q102 Jingle Ball held at Wells Fargo Center on Wednesday night (December 7) in Philadelphia, Penn.

The 19-year-old musician proudly performed her title track off of her new album, Skyscraper.

Demi recently told Glamour about the tune, Its 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 werent there for me when I went into treatment. It was a really dark time for me because I had only a few peopleI had surrounded myself with so many artificial friendships. Its about those people too.
