Demi Lovato Teases Secret "Dope" Collaboration

Healing her way to happiness through her music, Demi Lovato candidly talks to MTV about her upcoming album. The singer promises a sequel of sorts to her 2011 release Unbroken and its breakout single "Skyscraper."

"I'm continuing to let out a lot of things therapeutically on my music and I'm very thankful I have the opportunity to do that," Demi says.

"I've been working with incredible producers," she adds. "There's so many I don't even know who to name, but I do have a collaboration with somebody. I don't know if I'm allowed to tell but it'll be dope." Fans will have to wait to find out who Demi worked on a song with, but at least it's only a few weeks away until her new single "Heart Attack"
(March 4) comes out.

Who do you think is Demi's secret collaborator? And who would you like to see Demi work with in the studio?
