Anyone can grunt -- sorry, Leonardo DiCaprio -- but not many people can sing the hell out of a ballad like Demi Lovato can.
She released the emotional video for her song "Stone Cold," and Lovato is clearly going through a brutal heartbreak. She cries on a mountain. She wears a sweater in the bath for some reason. A fireplace cannot warm her. Eating bison liver is, admittedly, impressive, but it has nothing on having your heart ripped right out of your chest.
Devastation is truly Lovato in her element.
