Justin Bieber Flips Out at Paparazzi [VIDEO]

How do you put the cap on a really crappy week? Well, if you're Justin Bieber, just unload on some paparazzi.

That's just what happened Friday in London when Bieber, who'd been hospitalized just a few hours before after passing out during a concert, went ballistic on some photogs who were shouting insults at him. The singer apparently got so heated that he had to be restrained by his own bodyguards.

This incident is just the latest in a series of unfortunate events ever since Biebs set foot in London last week, including a run-in between his entourage and security guards at a nightclub where a birthday party for the singer was being held, and being hospitalized after falling ill during a concert Thursday night.

Bieber apparently rethought his latest move and sent out some tweets in an attempt at damage control. He tweeted:

Ahhhhh! Rough morning. Trying to feel better for this show tonight but let the paps get the best of me...Sometimes when people r shoving cameras in your face all day and yelling the worst thing possible at u...well I'm human. Rough week. Not gonna let them get the best of me again. Gonna get focused on this show tonight. Adrenaline is high now. Gonna put it on the stage. Only way someone can break u is if u let them.
