Justin Bieber was performing in Dubai last night when a crazy fan decided to run on stage and tried to attack him with a hug. Cue the bodyguard, who tackled the Bieleber immediately and knocked over Justin’s piano in the process. The weirdest part of it all? The music barely changes even while all hell breaks loose. Seriously, they flipped a friggin’ piano and yet somehow the music remains almost completely unchanged. But no, that’s totally how live music works, right?
