Jingle Ball - Demi Lovato - Heart Attack Live - 12/3/15 - Oakland, CA - [HD]

Here is Demi Lovato performing at 94.9 Jingle Ball in Oakland, CA at the Oracle Arena. The security made me stop recording during this song so that's why it just ends that way. This concert had amazing artists just like Shawn Mendes, Selena Gomez, Calvin Harris, Nick Jonas, DNCE, and Tove Lo. I even met Demi for the first time ever!!
