Bieber felt woozy toward the end of the concert and paused the show to receive “oxygen and treatment backstage,” according to the rep.
During the show, the pop star’s manager Scooter Braun told the crowd that Bieber was “backstage with the EMTs and the doctor” after getting “very light of breath,” in a statement posted on YouTube.
To the cheers of fans, Braun went on to say, “He has just told me … he’s going to come out and finish the show.”
After the concert, he was taken to a hospital as a precautionary measure.
“(Bieber was) just very tired from a long week,” said the representative, who wasn’t sure whether the singer still was in the hospital early Friday.
Bieber took to his official Twitter account after the incident, thanking fans for sticking with him: “getting better. thanks for everyone pulling me thru tonight. best fans in the world. figuring out what happened. thanks for the love.”
On Instagram, Bieber said he was “Gettin better listening to Janice Joplin” in a picture that showed the shirtless singer apparently lounging in a hospital room with a pair of headphones on.
Fan response on Twitter was universally supportive.
“Take it easy, try not to work yourself too hard,” said one fan.
“Hope you’re feeling better Justin, love you x,” said another.
This was Bieber’s third of four scheduled shows at the arena.
On Monday, he kept thousands of young fans and their tired, outraged parents up past their bedtimes after arriving on stage nearly two hours late for a sold-out show at the same arena.
Bieber was greeted by choruses of boos from the crowd.
Minutes into his performance, throngs of sobbing school-aged “Beliebers” were hauled away by parents desperate to catch the last trains home on a school night.
