Bieber Knocks Himself Out Slamming Into Glass Wall

More bad news for Justin Bieber: He knocked himself out after crashing into a glass wall in Paris. The singer walked headlong into the wall shortly before his last number at a private performance in an undisclosed highrise in the city. "It really hurt, and I felt light-headed, but my adrenaline pushed me through it" to finish the performance, he told TMZ. But the Biebs passed out cold for several seconds when he went backstage, and he was "unresponsive" for longer, he said. French doctors told him he had suffered a concussion, and should take it easy and keep someone nearby as he recovered, reports Reuters.

He said he later felt fine, though still had a headache. You "gotta laugh at yourself sometime," he said. It's a bad moon rising for Bieber. The singer is under investigation for possible assault in a recent confrontation with a photographer. Earlier this week, several fans were injured in a girl-crush at a free Bieber concert in Norway.
