I need some serious help finding this song, it's driving me nuts!

It's a hip hop song, it's sung by a girl, but I think there is like a featuring of a guy, but I'm not positive. It goes something like this:

When I'm down at the club, you'll be acting all nice, When I get on the floor, you'll be watching all night...

and...

then at some point it says work your body

vague I know, but if you could help me out I'd appreciate it. Thanks

the author is Timberaldn and the name of the song is something like work you body.,,, but i know the author for sure b/c someone asked that a week ago and i yahooed it and so yea

no i know exactly what you're talking about its
give it to me- nelly furtado featuring timbaland and justin timberlake

normally all you have to do is type as much of the lyrics you know into the google search engine, and type the word 'lyrics' behind it, and it, nine times out of ten will bring it up.
