The show must go on - even if Justin Bieber gets a concussion!

While performing in Paris on Thursday night, Justin ran into a glass wall backstage at a concert.

The singer spoke to TMZ after the incident, saying he passed out for around 15 seconds.

Doctors said the 18-year-old singer suffered a mild concussion and would fully recover, which his manager Scooter Braun also confirmed on Twitter.

"jb is gonna be fine. things happen. he is a trooper. canadian hockey player. tough kid. no issue," his manager Tweeted.

The singer was also quick to jump on Twitter following the show.

"Thanks for the love but there are alot of people out there who need prayers. im fine. just smacked my head and needed some water. all good," he wrote.

And Justin is also keeping his sense of humor about the incident.

"i will see u again Glass. I will have my revenge. BIEBER vs GLASS. MGM LAS VEGAS 2013. Lol," he joked. "that happened. at least we finished the show."

On Friday, Justin appeared to be on the mend, but also still feeling his rough night.

"moving a little slower today and running a little late. PARIS I will see u soon on that balcony," he wrote.
