Watch Justin Bieber fall onstage!

I'm going to hell for laughing this much...

Watch Justin Bieber fall onstage!

It's been a tough week for poor Biebs! First he gets beat up in Cleveland and then he falls flat on his face during a live performance. The Canadian-born pop star was walking across the darkened stage, appearing to pull his pants up (not surprised, they were basically half way down his legs!) when suddenly he fell through a trap door. The poor guy seemed to hit his head on the way down too... lol! Ok, we probably shouldn't laugh, but since he popped right back up after the fall, taking the embarrassing moment in his stride, we don't feel too bad about it.

Are we the only ones that have 0:06 on replay?? He just fell down like a rag doll! Luckily he doesn't seem to be too badly injured, saying ""Good thing I'm like a cat and landed on my feet. That scared the f**k outta me!" Although we can't help but notice he seemed to hit his head on the edge of the trap door. Hmmm... hopefully it knocked some sense into the dude!
