Justin Beiber's week in London couldn't be any worse. Of course we all know he had the worst 19th birthday party ever, plus he was booed onstage after starting his show late the other night and then, to top it all off, last night he fainted during the middle of his song "Beauty and a Beat" and had to be given oxygen.

Bieber appeared to get light headed and ended up walking off stage (the first video below) where he collapsed and was given oxygen by the EMTs. After he stumbled off stage, Bieber's manager, Scooter Braun came out to tell the audience that the Biebs would be back shortly(the second video below). He was urged by doctors not to return to the stage but after a twenty minute rest, Bieber reappeared to finish his show in front of the crowd at London's O2 Arena. He was taken to the hospital after the show was over.

He reasured all his Beliebers he was okay by tweeting "getting better, thanks for everyone pulling me thru tonight. best fans in the world. figuring out what happened. thanks for the love."

An hour later he tweeted again, this time posting a picture of him shirtless (the picture you see above) and  in a hospital bed, saying "Gettin better listening to Janice Joplin."
