Justin Bieber has been very busy lately, which has now showed it's dark side for him. Last night Justin was sent to the hospital in London, after having a hard time breathing. Justin felt woozy during his entire show, and when he only had four songs left to sing, he went backstage and collapsed. He was brought into a private room and had oxygen from the emergency doctors. They insisted he should go directly to the hospital, but Justin said he "had to finish the show for his fans." Justin completed the show and had huge standing ovations, but was transported to the hospital straight afterwards. Justin is okay at the moment, but the doctors want to make sure they really evaluate him before he can leave. (tmz)
