Justin Bieber Suffers Concussion After Paris Concert

Singer hits his head on a glass wall during his performance and later passes out

Before you start freaking out, Justin Bieber is OK. We repeat, he is OK (but we were so worried, too!).

E! News confirms that the 18-year-old—who has been making numerous headlines lately—suffered a slight concussion after performing in Paris tonight.

So what happened?!

It turns out that Biebs hit a glass wall in between songs (those can definitely be tricky) and felt a little disoriented. Being the dedicated young worker he is, Bieber finished the concert, but passed out for about 15 seconds in his dressing room afterward. Gasp!

Once again, J.B. is all right and in fact, he's already laughing the whole thing off.

"i will see u again Glass. I will have my revenge. BIEBER vs GLASS. MGM LAS VEGAS 2013. lol. #GottaLaughAtYourself," he tweeted.

Bieber's manager Scooter Braun also took to Twitter after the situation occurred and wrote, "jb is gonna be fine. things happen. he is a trooper. canadian hockey player. tough kid. no issue."

"now that he is ok i can say this... BIEBER and GLASS...they dont like eachother," Braun continued. "#ItHappenedAgain...but the fact that he still went and finished the last song and KILLED IT. That was impressive. #TrueProfessional"
