Bieber gets concussion

Bieber 'attacked'Singer tackled bya policeman

Teen sensation smashes head on a glass wall...

Justin Bieber has concussed himself on a glass wall in France.

The Boyfriend singer was performing in Paris when he walked into a glass wall backstage and knocked himself out.

The teen sensation told TMZ:

"So basically... I'm in Paris and I'm like, performing on the tallest building in Paris.

"There's a glass wall behind me, but there's a railing behind the glass, and so, I went to reach for the railing and I hit my head on the glass.

"It really hurt and I felt a little light-headed, but my adrenalin, I feel, pushed me through it and I performed my last song. 

"After that, I went off stage and I immediately felt really weak. I was walking down the stairs and I passed out for like, 15 seconds... I feel good, I have a little bit of a headache, but I feel fine. 

"I mean, you've got to laugh at yourself sometimes."

The star, who was once videoed hurting himself walking into a revolving glass door, confirmed that he had seen a doctor and had been diagnosed with concussion.

He added:

"I guess me and glass windows don't really go together."

It was recently revealed that Bieber may face six months in prison if allegations that he had an altercation with a photographer are true.

Calabasas police want to speak to the performer about the incident with a paparazzi photographer after he claimed that the singer "physically battered" him.
