When she's not busy hobbling around on her crutches lately, Demi Lovato is hard at work on her fourth studio album and we finally have some details on it! In a short teaser, the songstress revealed that her first single off the as-yet untitled album is called 'Heart Attack,' and it's due out March 4.

In the short 30-second clip promoting the uptempo new track, the 'Unbroken' songstress addresses her troubled past. "For awhile, I could tell when people talked to me, they knew my story," she says.

Demi's label has also confirmed that 'Heart Attack' was produced by Grammy-nominated duo the Suspex, who also co-wrote the tune with Demi herself, Sean Douglas and the very talented Nikki Williams.

What else should we expect from her new batch of tunes? "These are songs about the celebration of life and how rewarding it can be," Lovato explains. "This is what this album is about."

Lovato pretty much confirmed what we already know. She tweeted back in January about her uptempo new material: "Rang in the New Year last night in Mexico having a dance party to my new music with my best friends.. I'd say that's a pretty awesome NYE." Demi also said some of her new music would have a "throwback" vibe.

All this talk has made us really excited for DD's return to music!
