Demi Lovato kicked off her performance of "Sorry Not Sorry" at Sunday's American Music Awards from her seat, shortly after arriving with AMAs date, Virginia Rep. Danica Roem. After taking to the stage, Demi was joined by an army of dancers clad in matching black outfits. It's too bad the boys of BTS didn't follow her to the stage, because it turns out they know all the words to "Sorry Not Sorry" and were so into the performance, they danced from their seats. See?
Demi has a chance to return the love later in the show, when BTS takes to the AMAs stage. Get excited!
