Listen to Demi Lovato on iHeartRadio

Get ready, Lovatics! Demi Lovato announced on her Facebook page and on Twitter that she's dropping a brand new single, "Heart Attack," on March 4!

In less than an hour after the big announcement,  #LovaticsAreHavingAHeartAttack became a Worldwide Trending Topic on Twitter - proving the power of Lovato's incredibly devoted fanbase. Lovato's previous song "Give Your Heart A Break" went #1, so maybe she's hoping keeping the heart theme with "Heart Attack" will pick up where GYHAB left off.
