Watch Demi Lovato ‘Heart Attack’ Official Music Video

The wait is over! Demi Lovato has released the official music video for her single 'Heart Attack'. Watch it right here!

The video features Demi in various spots, but to us it seems like it's her battle between good and evil - but we could be wrong. It's a bit Jekyll and Hyde at times, which is pretty cool. We expected nothing less from Ms. Lovato.
