Demi Lovato and Nick Jonas recently played at KeyArena during a stop in their Future Now Tour. Nick was up first and Demi was clearly the headliner, as they took turns on the stage throughout the show. They both appeared for “Stone Cold,” with Nick on piano. Later in the evening, surprise guest Bea Miller came out and sang with Demi, Nick did a few songs on his own, and the show wrapped up with Demi back on stage for three more songs. LA-based Chord Overstreet opened.
