Jennifer Aniston, Gerard Butler's dirty pictures revealed!

jennifer-aniston-gerard-butler-dirty-W-pics-zap2it.jpg Gerard Butler and Jennifer Aniston posed for some very hot pictures to publicize their  romantic comedy, "The Bounty Hunter."

In the W magazine voluminous layout, Gerard gets gruff while Jen oozes sex appeal wearing skimpy lingerie in the desert.

The layout is ironically shot by the same photographer ( Steven Klein) that shot Brad Pitt and Angelina Jolie's sexy shoot to promote "Mr. and Mrs. Smith." Talk about a 'gotcha.'

But this may be the first time we will not be emulating Jen's hairstyle. To be frank, we are not prepared to wear sand, sweat, gel and hairspray in our unwashed hair.
