Hot damn, Justin Bieber!
We were NOT expecting this!
Check out footage from the pop star's recent performance in Mexico City, during which he decides to break it down, and show off some SERIOUS moves (above)!
…and the crowd goes WILD!
Granted, he could probably read out lout from a geometry textbook and make those Bieblievers lose their shiz, but this is definitely warranted!
Has Usher been teaching you some moves, boy?! LOLz!
