Evidence keeps mounting that Justin Bieber is losing it: After passing out onstage last night (and then tweeting a shirtless photo of himself in his hospital bed), this morning in London Bieber flipped out on a photographer, reports pretty much every gossip outlet. Bieber was leaving the hospital when his bodyguards shoved waiting paparazzi out of the way. One cried assault and started cussing Bieber out. Bieber responded in kind, lunging at the photographer and screaming that he would "[bleeping] beat the [bleep] out of you." Click to see pictures of Bieber being restrained by his own security guy.
