Justin Bieber suffered a concussion Thursday after he ran into a glass wall during a concert in Paris, TMZ reports.
The 18-year-old pop singer had been performing but then went backstage in between songs and hit the wall. Bieber told the site that he was disoriented, but went back and finished his concert. However, Bieber passed out for 15 seconds after his set as he returned to his dressing room.
Justin Bieber wanted for questioning in alleged battery incident
Doctors diagnosed him with a concussion, but said he'll be OK.
Bieber also ran into a glass door back in May 2010. "I guess me and glass windows just don't work," he told TMZ.
Bieber was in the spotlight earlier this week after a paparazzo claimed the teen sensation assaulted him over Memorial Day weekend. He is wanted for questioning by Los Angeles-area police.
