LMAO Justin in a leotard and heels is just genius!

We are officially obsessed with Beyonce's new vid for Single Ladies - Put A Ring On It. If you love a dance routine this is the one you need to bust out on a Saturday night!

And when we heard that she got her (male!) choreographer to don black leotard and heels to be one of her back-up dancers we youtubed it even more!

But then we came across this - Justin Timberlake giving the routine his very own, er, touch!

Who knew JT was so hilarious?!

And he's not a bad dancer, anyone who can bust moves in serious heels is a legend in our eyes.

Saturday Night Live is massive in the US and launched the careers of Will Ferrell and Sarah Silverman. You might recognise Paul Rudd in this clip - he played Mike in Friends and was Paris in Romeo + Juliet.

Now check out the real thing. How much do we LOVE Beyonce? Altogether now...'All my single ladeees'
