TMZ - Justin Bieber was knocked out cold after running into a wall of glass during a concert in Paris. We just spoke with Justin, who said he was performing on stage, and in between songs he walked backstage and hit the glass. He says he was disoriented, but went back on stage and finished his set. As he walked to his dressing room he passed out cold, for around 15 seconds. Doctors say Justin suffered a concussion but he’ll be ok.

Guts of a burglar. No other way to describe it. Biebs suffers a concussion mid show in Paris. Does he let it slow him down? Does he cry about it? Nope. He just wills his way through the show and then passes out cold when it’s over. You can say whatever you want about the Biebs but you can’t doubt his toughness and mental fortitude. If you’re gonna beat him you’re gonna have to kill him.
