Demi Lovato is all smiles as she arrives at the Good Morning America studios early Wednesday morning (April 10) in New York City.
The 20-year-old actress/singer was nice enough to stop and sign some autographs for fans who were waiting all night.
“Early morning tomorrow….performing Heart Attack on @gma tomorrow at 8am in Times Square!!!” she tweeted.
The day before, Demi released the music video for her latest single “Heart Attack.”
