Justin Bieber is nursing a sore head this morning - not because he's gone out on the lash, but because the clutz managed to knock himself out at a gig.

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

Justin told US website TMZ that he passed out for 15 seconds during the concert.

"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," he said.

"It really hurt and I felt a little light-headed, but my adrenaline, I feel, pushed me through it and I performed my last song. After that, I went off stage and I immediately felt really weak."

He continued: "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 Biebs has bit of a history with glass, as he previously had an accident back in 2010 where he was filmed walking into a revolving glass door.
