We already saw Justin Bieber cover Usher and Matchbox Twenty in a medley at the Georgia Music Hall of Fame honoring his voice coach Jan Smith, where he was also bestowed with a Horizon Award for his achievements as a young musician. And it certainly looks like the Ferrari-demolishing superstar was having the time of his young life as he goofed around with his dirty-dancing buddy behind the scenes. (The pair was much more serious when posing with Selena Gomez.) Could it be that this night in Atlanta topped the Biebs' silly Fashion Night Out? From the looks of it, maybe!
