It's short and sweet, especially if you're not a fan of the Biebs...

Last night Justin Bieber was performing for a raucous crowd in Dubai.  Some male fan jumped on stage and attacked Bieber while he was playing the piano.  It looks like an excited fan, but the Bieber camp has been handling it like an assault.  The video gets so intense that the piano actually FALLS OVER during the attack!  Check it out here!
