After performing "Heart Attack" for the first time at an Orlando concert on March 2, Lovato will tour Asia in the second half of the month. According to Snow, the "Heart Attack" music video will be out sometime in April. The label has yet to set a street date for the album, but he says it will expand Demi’s appeal beyond her core, primarily teenaged "Lovatics" fanbase. "It's going to be a very consistent record in terms of its feel," Snow says. "Even though she's only 20, there's certainly an effort to broaden her demographic."
