Lights, lasers, treadmill, ACTION!!
Usher can't-can't-can't stop KILLING his live performances.
Watch the man make his way through Numb, Climax, Can't Stop Won't Stop in the FIRST AMA performance of the night (above)!
Sure, he misses a few notes, but can you blame him?! He's running on a motherf*cking treadmill! GET OVER IT! :)
