After offering up several previews, Demi Lovato has released the full video for her new single, “Heart Attack.”

Directed by Chris Applebaum, the song is the lead single from her forthcoming new album, “Demi,” which is due May 14.

"I'm taking on a different look this time around," Lovato told MTV News in February. "I feel like I have my own thing going, like rocker-chic sophisticated, just a different kind of fashion style this time around."

“Heart Attack” recently debuted at No. 1 on the iTunes chart in 18 countries (including the U.S.) and No. 12 on the Billboard Hot 100 chart (the second-best Billboard debut of the year).
