Justin Bieber has suffered a concussion after stumbling backstage during a performance in Paris.
The teenage heartthrob's injury was the latest incident in a chaotic tour of Europe.
Justin confirmed to gossip website TMZ.com he fell into a glass wall at the Paris venue and felt light-headed but was able to perform his last song before going backstage and passing out for 15 seconds.
Justin later tweeted: "Just smacked my head and needed some water. All good. I'm Canadian. We are tough. The show must go on."
The previous day there was chaos in Oslo when Justin offered free tickets to see him perform. 49 fans were reportedly hurt in the stampede for tickets and 14 were taken to hospital for treatment.
Justin stepped in to try and help, tweeting: "Norway - please listen to the police. I dont want anyone getting hurt. For the show to happen u must all listen to the police."
