Justin Bieber lost his temper Friday morning in London — and he was caught on tape losing his cool.
Bieber apparently made contact with a paparazzo as he barreled out of his hotel, leading the man to shout, "That's assault" and let fly with a couple of profane statements, one urging the singer to, ahem, go back to America and the other calling him a "little moron."
The 19-year-old had gotten into his car by that point, but apparently heard the insults and came flying out, dropping F-bombs of his own and threatening to beat up the photographer.
Strapping bodyguard types in Bieber's entourage contained the upset singer and wrangled him back into the vehicle before anything came to blows. But the insults were still in the air.
