Justin Bieber hysteria has reached an all new high. Currently in Europe to promote his June 19 release of Believe, European fans just can’t seem to get enough of Bieber. While numerous fans have been injured this week as pandemonium broke while waiting for his performance, it turns out Bieber faced injury himself.

Last night Bieber suffered a concussion during a show in Paris.

“I went to reach for the railing and I hit my head on the glass,” Bieber told TMZ. “I guess me and glass windows just don’t really go together. It really hurt and I felt a little lightheaded but my adrenaline pushed me through it and I performed the last song.”

Bieber said he felt really weak and passed out while walking down the stairs after the show.

“You have to laugh at yourself sometimes,” he said and admitted that he is feeling better.

Bieber took to Twitter to thank his fans, and surprise his own mother with his condition.

the fact you all knew what happened before my mom even did is impressive. lol. I have amazing fans. very grateful for your love.

At a concert in Oslo, Norway, earlier this week nearly 50 fans were injured, 14 of which were taken to the hospital. Meanwhile, police threatened to declare a State of Emergency as thousands of fans descended on the city. In an effort to control the crowd, Bieber once again took to Twitter.

NORWAY – please listen to the police. I dont want anyone getting hurt. I want everything to go to plan but your safety must come first…
