Not only did she sing "Give Your Heart a Break" for the crowd, she talked fashion and told us about her new album and sound! Oh and X-Factor's Fifth Harmony showed up too!
"'Heart attack' is kind of a different sound, I'm really taking advantage of good ole' American pop music...I'm also using this album to express what's important to me....my heart is basically on my sleeve on the entire album," she said.
Hmm, does that mean we can expect some juicy relationship deets in her new stuff?
She also spilled about her favorite happy place....the studio, of course!
