As Justin Bieber left his Central London hotel on Friday and made a run into his SUV, he knocked into a waiting photographer and following the incident curses where thrown by both parties as Bieber tried to fight the photographer.

The photographer was upset by the physical contact and claimed he was assaulted. He began to curse out Bieber, who was already in his waiting vehicle, by saying, "f**k off back to America," and "f**king little moron"

The 19-year-old Beauty and a Beat singer heard the insults, opened his SUV door and attempted to attack the photographer. He was held back by his bodyguard but yelled, "What the f**k you say?"

The photographer replied, "You heard what I said ... you heard what I f**king said, mate."

"I'll f**king beat the f**k out of you," Bieber said.

Bieber tried to punch the photographer but his bouncers kept him in check, eventually pushing him back into the SUV. His car then left the scene.
