A photographer screamed that he was assaulted and started to curse at Bieber, who had already made it inside his vehicle.

"F*ck off back to America!" the photog yelled "F*cking little moron."

Bieber who stands 5'7, and probably doesn't weigh more than 140 pounds hopped out of his ride and tried to go after the photographer.

"The f*ck you say? What did you say? I'll f*cking beat the f*ck out of you," Bieber said, while being restrained by one of his bodyguards.

"Lose your f*cking bouncers," the cameraman replied. "Come back you prick!"

Poor Justin Bieber. First he has his "worst birthday" ever, now he's getting booed by his own fans after coming on stage two hours late at London's O2 Arena.

He was two hours late for his opening night, forcing hundreds of parents to leave with their children on Monday night before the singer even came on stage. The 19-year-old has been slammed on Twitter for his 'disgusting behaviour' which saw hundreds of dedicated Bieber fans walk out of the arena heartbroken, despite waiting hours for his arrival.

Photos taken last night show a shirtless Biebs enjoying yet another night of clubbing while on tour in the UK, but apparently the fun didn't stop there!

Bieber left his hotel at 3 A.M. to meet up with rumored-girlfriend Ella-Paige Roberts Clark, along with an unnamed mystery girls. Dismissing this as just a random birthday rendezvous? Keep in mind that these same two girls, AND another mystery girl, were caught spending the night at Bieber's hotel just a couple days earlier after some heavy partying. Paparazzi even caught the girls leaving in the same clothes they arrived in just after Justin departed later that morning....ahem...you do the math!

Happy Birthday, Justin! Hope you will leave London with as many lays as years under your belt!
