We have no idea why Jessica Simpson is featured in the latest issue of Vanity Fair.
But we definitely know why Megan Fox is on the cover of next month's Esquire:
(We guess she's starring in some movie titled Transformers: Revenge of the Fallen, as well, this summer.)
Put a pot of coffee on and prepare to ogle, fellas. You're gonna need awhile to appreciate this image of Fox, clad in nothing but an overcoat and black lingerie...
We'll post more (and more and more) pics of Megan Fox from her Esquire spread when the issue is released on June 10.
