That picture above is of him in hospital, 'btw'.
In the middle of his third 'gig' at the 02 this week, the 'Mistletoe' hitmaker left the stage as he was feeling woozy, before fainting.
"Justin's got very light breath," Scooter Braun told the crowd, in a video posted on TMZ. "The whole show he’s been complaining, He’s backstage with the EMTs and the doctor."
Like the real trooper that he is, he came back onstage and finished the show before going to hospital as a precaution.
He found enough strength to tweet the following:
getting better. thanks for everyone pulling me thru tonight. best fans in the world. figuring out what happened. thanks for the love

This rather helps with the whole 'Justin has no respect for his fans' thing, doesn't it.
