Gurl just doesn't quit.
Even if she is wearing all black, she has perfected the art of lighting up ANY stage she hits.
And could this single be anymore AH-mazing??!!
We haven't even heard the rest of her new album, Demi, yet, but if it has even an ounce of the intensity Heart Attack has than we know we'll be blasting it over and over and over again!
Ch-ch-check out the young diva work it out (above)!!!
