Oh dear, we knew Justin Bieber fancied himself as a skateboarder, but we'd never actually seen any video evidence of his errr... skills before now.

Apparently he treated a group of fawning fans to this demonstration of his "supreme" technical prowess in New York shortly after Christmas.

"He has one of his heavies keeping the crowd back"

We love the way he has one of his heavies keeping the crowd back while he shreds - if only we could all have that kind of backup when hitting the streets eh?

But the best thing about it? The way the cameraman (and everyone else watching) shouting "yeah" and "you go bro!" as he fails to nail it...

And what's with that dress?
