Justin Bieber“s feeling better — in fact, he”s feeling good enough to FIGHT … “cause he just went after a photog in London … and screamed, “I”LL F**KING BEAT THE F**K OUT OF YOU.”
Bieber — flanked by bodyguards — was leaving the Central London hotel moments ago … and in the mad scramble to his SUV, he made contact with a waiting photog.
The photog — clearly upset by the physical contact — immediately claimed he was assaulted … and began to cuss out Bieber, who was already inside the waiting SUV.
But Bieber clearly heard the photog”s insults (“f**k off back to America”, “f**king little moron”) … “cause the singer opened his SUV door and sprung out of the car … trying to attack the photog.
While Bieber”s bodyguard held him back, the singer screamed … “What the f**k you say”
The photog shot back — “You heard what I said … you heard what I f**king said, mate.”
Bieber replied, “I”ll f**king beat the f**k out of you.”
Justin tried to swing at the photog, but his bouncers kept the singer at bay … and eventually pushed him back inside the SUV.
The car left the scene without further incident.
Bieber just tweeted about the incident … saying, “Ahhhhh! Rough morning. Trying to feel better for this show tonight but let the paps get the best of me.”
