Justin Bieber challenges paparazzi to a fight.

Justin Bieber challenges paparazzi to a fight.

Justin Bieber must still be delirious from his fainting spell at London’s 02 arena. He jumped out of his SUV as he was leaving his hotel this morning and threatened to “beat the fu*k out of” a paparazzi, who was cursing up a storm as well.

Bieber’s behavior was all the more odd because most of the incident took place after he got in the car. He actually opened the door and challenged the photographer.

“Ahhhhh! Rough morning. Trying to feel better for this show tonight but let the paps get the best of me,” the 19-year-old tweeted afterward.

Fortunately, one of his bodyguards kept a cool head and literally lifted the pint-sized singer and pushed him back into the car.

Bieber was leaving is hotel flanked by two body guards. He crouched down behind one as he exited the door and made his way to the car. But a photographer started complaining after one of the bodyguards tried to push photographers out of the way.

If Bieber thinks US photographers are bad, London paps are unbelievably surly. The photographer claimed at first he was assaulted, then he verbally assaulted the Biebs, yelling “Fu*cking little cock. Fu*k, go back to America!”

He also called the teen sensation a “f**king little moron.” That was enough to draw Bieber out of the car.

“What the f**k you say?” Bieber shouted.

“You heard what I said; you heard what I fu*king said, mate,” the pap replied.

That really peeved the Biebs: “I’ll fu*king beat the f**k out of you.”

Justin tried to swing at the photog, but his cool-headed bodyguard got between him and the photographer.

Once Bieber was back in the car, it pulled out without incident.
