Justin Bieber may have a baby face and appeal to the tween set, but that doesn't mean he should be trifled with. The singer got into a scuffle with an aggressive paparazzo yesterday that resulted in an ambulance being called (to treat the pap) and Justin losing his shoe and hat. Girlfriend Selena Gomez arrived on the scene to aid Justin in his hour of need. Neither looks very happy about it.
Bieber's got a lot of fierce competition in the paparazzi brawl department. After the jump are some of our favorite kerfuffles!
