Justin Bieber punched a man in the face on his way to a concert tonight in Barcelona after that man repeatedly reached into the Biebs’s car window and tried to touch his face. (And you guessed it! TMZ has a video of the incident.) This is the most aggressive move from the pop star who has become increasingly combative with fans: Back in May, Bieber declared a moratorium on fan photos, saying they made him feel like “a zoo animal,†and in October he asked an arena to cut the screaming, because it was “just so obnoxious.†A few days after that, Bieber exited the stage when the Beliebers, once again, failed to heed his pleas to quiet down. It sounds like a good time for the Biebs to take five on a private island somewhere soon. Maybe he can ask Kanye to come with.
