Justin Bieber went a little crazy on a photographer in London earlier today.

To be fair, the paparazzi guy was being very rude and unprofessional. You can tell he was doing his best to push Justin into doing something stupid. Unfortunately, it worked.

Watch the video of Justin lunging at the pap and cursing at him while his security holds him back and throws him in the car.
