Justin was leaving the Central London Hotel when a waiting photog - upset with the Biebs' bodyguards -- began to shout out insults, including, "f**k off," "[go] back to America," and "f**king little moron."

The 19-year-old superstar opened the door of his SUV and yelled, "What the f**k did you say?"

The paparazzo replied, "You heard what I f**king said!" to which Biebs - who was being held back by his bodyguard at this point - shot back, "I'll f**king beat the f**k out of you!"

Justin's security forced him back into the car, and they took off.

Adding, "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."

Piers Morgan also chimed in on Twitter and he thinks Justin's angry reaction was justified.

"I'm backing @justinbieber in paparazzi-gate. That photographer was a revoltingly rude, ignorant, foul-mouthed hooligan," he wrote on Friday. "Most paparazzi I encounter are nice, polite guys earning an honest living. Idiots like the @justinbieber goon give them all a bad name."
