Backstage, he was given oxygen as he took a 20-minute break; then he hit the stage again to finish the show, against doctors' recommendations, Reuters reports. Bieber had been "very light of breath," his manager told the audience. "The whole show he has been complaining." Afterward, the singer was hospitalized. "Getting better," he tweeted, along with a shirtless self-portrait from the hospital bed, per E! Online. "Thanks for everyone pulling me thru tonight. Best fans in the world." Some of those fans, however, have taken to tweeting with the hashtag "#justintakeabreak."
