Justin Bieber took a spill on stage last night (Thursday) in Saskatoon, Canada. The Biebs was strolling a on stage and adjusting his pants when he suddenly fell in a trap door. The fall was punctuated by a loud thud made by the microphone he was holding. But a few seconds later, Bieber crawled back out and seemed to be okay.
