Demi Lovato's First Performance Since Father's Passing On Good Morning America!

What a trooper!!
Demi Lovato performed her hit single Heart Attack on Good Morning America earlier Friday morning, making this her first performance since her biological father’s death.
Following news of his tragic passing, the X Factor judge had stepped away from her work duties to mourn her loss. Yet, though we’re sure this is a very difficult time for the star, Demi is back to being her stellarly professional self.
Ch-ch-check out her performance (above)!
She later performed Made In The USA and Give Your Heart A Break.
You sounded great, lady! Keep that chin up!
