" Demi Lovato has confirmed the title and release date of her new single. The singer will release &amp;#039;Heart Attack&amp;#039; on March 4 as the lead cut from her upcoming fourth album, which has yet to receive a title.      The accompanying artwork sees Lovato peering from the side of a white wall, with her hair up and pushed forward into a choppy fringe. &amp;quot;For a while I could tell that when people would talk to me they knew my story,&amp;quot; Lovato explains in the trailer. &amp;quot;I think I&amp;#039;ve opened up more on this album.   &amp;quot;My life began to evolve and I started to grow. These are songs about the celebration of life and how rewarding it can be. This is what this album is about.&amp;quot; Lovato&amp;#039;s new album will serve as the follow-up to 2011&amp;#039;s Unbroken, which reached number four on the US Billboard 200 chart.
