Follow-up to 2011's "Unbroken" album is due out in late spring/early summer.
After scoring the biggest hit of her career in 2012 with "Give Your Heart a Break," Demi Lovato started the campaign for her next album with her best sales week ever for a song. "Heart Attack," the lead single from her forthcoming, as-yet-untitled fourth full-length, due out in late spring/early summer, rockets to a No. 12 debut on this week's Hot 100 chart with 215,000 downloads sold, according to Nielsen SoundScan.
“Heart Attack" was originally set for a March 4 premiere on Ryan Seacrest's syndicated radio show, but leaked online on Feb. 24, springing Hollywood Records' marketing department into early action. "I was having an Oscar party at my house when [the leak] went down, so I had to excuse myself and have a conference call," Hollywood Records' head of global marketing Robbie Snow recalls with a laugh.
