A lingerie-clad and then topless Eva Mendes is all over shirtless model Jamie Dornan in a racy new Fall 2009 campaign for Calvin Klein jeans and underwear.

Shot by world-renowned photographer Steven Klein, the ads will appear in billboards as well as in magazines as Jeans ad inserts, four-page ad units and covers of Lucky, Elle, GQ, Vanity Fair, W, Nylon, Details, Interview and InStyle.

They're not as racy as the Eva Mendes nude ads for CK that were banned last year, but still, she and Dornan are gonna be heating up those publications ...

We have no idea who Jamie Dornan is, but we do now. He is one lucky individual for getting Eva Mendes all pressed up against him like that. Jerk.

The woman some say is the world's most desirable certainly makes a compelling case for that honor with these ads, which conveniently for Calvin Klein, may require readers to begin thinking about a new pair of jeans pretty quick.
