734219086_919093Justin Bieber has had a rough week.

After celebrating his “worst birthday” on March 1 and angering concertgoers at London’s O2 Arena on Monday when he was late to the stage, the pop singer had to take a break from his concert on Thursday to receive “oxygen and treatment backstage,” his representative said.

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 and was released early Friday.

“He’s been released from the hospital early this a.m. after a check-up and while he’s feeling a little under the weather, he’s planning on going ahead with tonight’s show,” the representative said later in the day.

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.
