Demi Lovato brought down the house with her haunting performance of Lionel Richie's "Hello" at the Grammys tonight. Dressed in a sleek blazer, Demi performed as part of a tribute for the four-time Grammy winner. And she did him proud.
Richie was cheering her on before he took the stage to join Demi, John Legend, Meghan Trainor, Luke Bryan and Tyrese for "All Night Long."
And excuse us while we listen to this Demi clip all night long.
