LONDON (AP) – The show went on – but not without a bit of health drama for Justin Bieber. The singer spent some time in the hospital last night in London after fainting backstage during a show at the O2 Arena. A spokeswoman says the singer had to be given oxygen and had took a 20-minute break as his show wound down. A concertgoer says Bieber complained he couldn’t breathe and needed water. He kept going, but eventually had to be helped offstage by a dancer. Videos of the show posted online show Bieber’s manager telling the audience Bieber was “very low of breath” – but would finish. Some fans gasped, others cried – and others kept cheering for him to come back. Bieber is to do four shows at the O2, including one tonight. As of now, that show is still on the schedule.
