The Artist: Justin Bieber
The Fall: During a concert in London in November 2009, Biebs ran onto the stage, tripped momentarily, and broke his foot—before finishing the song he was performing and leaving the stage.
How Embarrassing Was It? The actual "fall" wasn't that embarrassing because he didn't end up face first on the ground. But, ironically, if he had fallen, he probably wouldn't have ended up breaking his foot, which was the really embarrassing part of the whole incident.
