Justin Bieber collapsed at his London concert, then went to the hospital for observation.
As he left the hospital on Friday morning, he lost his temper— 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.
One of my favorite performances on last night's "American Idol" came from contestant Angie Miller, who sang the ballad "Never Gone."
In fact, the women have really been delivering some amazing performances this season, despite this season getting the lowest ratings that the show has ever had.

Adrienne Maloof has no problem landing men -- but last night in Los Angeles, she paid $25,000 for a makeout session with Mario Lopez ... and it was all for a good cause.
Maloof and Lopez were part of the Have a Heart Auction in Honor of Zeke (HelpZeke.com) ... an event to raise money for Zeke Kendall, a 20-year-old man who underwent heart transplant surgery last month.
The auction was held at Mixology at The Grove.
