Every time we hear Demi Lovato sing, her insane voice nearly gives US a Heart Attack.
The returning X Factor judge gave a stellar performance of her new hit single on Jimmy Kimmel Live and she worked it … AS ALWAYS.
She is the definition of FIERCE.
Can you believe that she was actually sick on top of it??!
So much talent, it would scare us if she wasn't so lovable!
Ch-ch-check out the diva work that stage (above)!!!
And watch her darling interview…AFTER THE JUMP!!!
