The incident, which was caught on camera on Friday, has now made its way in the video sharing site YouTube.
It shows the singer losing his cool after he bumped into a few Paparazzis who provoked him by yelling “f**k off back to America” and “f**king little moron.”
Bieber heard what was said, opened the car door and said, “I’ll f**king beat the f**k out of you.” The young Canadian crooner then lunged at photographers, but was restrained by his bodyguard.
Bieber confirmed the news to his fans via his Twitter account:
“Ahhhhh! Rough morning. Trying to feel better for this show tonight but let the paps get the best of me. 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.”
