Justin Bieber hit the 2015 American Music Awards stage to bring the heat (and the rain) to a medley of his biggest tracks from his latest album, Purpose. Bieber kicked it off with an acoustic cover of his ?What Do You Mean?? followed by ?Where Are Ü Now?, his collaboration with Skrillex and Diplo that took home the AMAs? ?Collab of the Year? trophy. A sky of rain then opened up above the stage for the singer?s grand finale of ?Sorry?.
