Listen to Demi Lovato on iHeartRadio

Demi Lovato chatted with the crew at Miami's Y100 where she opened up about her new single. "Heart Attack" was released quickly, and maybe a little too quickly because the unexpected release occurred because the song was actually leaked! 

Demi talks about her leaked single, opens up about X-Factor (if she'll return), and her thoughts about Britney leaving, and who should replace Khloe Kardashian now that she was let go.
