Justin Bieber was hospitalized in London last night after collapsing backstage during his concert at the O2 Arena. With four songs to go, Justin was taken to a private room where he was treated by oxygen and advised not to go back on stage. TMZ reports that Justin insisted he needed to “finish the show for his fans.” Bieber’s manager Scooter Braun came out and told the crowd, “Justin's got very light of breath. The whole show he’s been complaining. He’s backstage with the EMTs and the doctor." Moments later Justin completed the show, and got a huge ovation from the crowd. Once done he was transported to a hospital where he received treatment. Bieber later tweeted a shirtless photo of himself, along with the post, “getting better. thanks for everyone pulling me thru tonight. best fans in the world,” adding, adding, “figuring out what happened. thanks for the love.” Justin’s stint in London hasn’t been an easy one. Earlier this week he was booed by the crowd for starting his show two hours late.
