Bad Week For Justin Bieber Wraps With Hospitalization and Fight With Paparazzi

Justin Bieber on a rampage!

Bieber lashed out today in London, going after a photographer who was cursing at one of his bodyguards. It happened as he was leaving his hotel.

His bodyguards cleared the way and he hopped into his van. Then, the furious pop star suddenly jumped out. He was held back by his guards.

Once he had calmed down, Bieber took to Twitter to explain himself, tweeting: "Ahhhh! Rough morning. Trying to feel better for this show tonight but let the paps get the best of me... Sometimes when people r shoving cameras in your face all day and yelling the worst things possible at u... Well I'm human. Rough week."

He's right about it being a rough week. The temper flare-up came just hours after a scary moment for Bieber at his concert in London last night when the 19-year-old pop star doubled over and then slowly walked off the stage.

Thousands of his young fans were left in shock, screaming and crying. He reportedly fainted backstage and was given oxygen. His manager talked to the packed arena.

"Justin got very light of breath. The whole show he's been complaining, and he's backstage with the EMT's and the doctor. They are telling him that they want him to go see somebody and see what's going on with his lungs."

Bieber managed to finish the concert after resting. Immediately after, he was taken to the hospital. He assured his fans he was all right, tweeting a shirtless photo from the hospital with the message, "Getting better. Thanks for the love"

Bieber says he'll use the "adrenaline" from the dust up with the paparazzi today to fuel his concert tonight in London.
