Justin Bieber explodes at photographer, threatens to 'beat the f**k' out of him! (Warning: NSFW language)

JUSTIN BIEBER got into an altercation with a photographer in London on Friday.

As he left his hotel, he rushed to a waiting car but accidentally knocked a photographer as he jumped into the vehicle.

The photographer started swearing at Justin and said “F off back to America.” That wound Justin up and he opened the car door and launched himself at the man, yelling, "What the f**k did you say? What did you say? I'm gonna f**king beat the f**k out of you."

Justin’s minders held him back and pushed him back into the car.
