Eva Mendes and model Jamie Dornan are back in action for Calvin Klein Jeans.

The sexy duo, who are currently romping through the company's fall campaign, work their barely-clad magic again for the Spring 2010 ads shot by famed fashion photographer Steven Klein.

And if you thought the previous Jeans and Underwear ads were hot (and controversial), the upcoming ads should be even more so.

A company insider told StyleList that the two are much more comfortable with each other now: "The rapport between them was great for the second campaign because they became great friends after shooting their first campaigns together for Calvin Klein Jeans and Calvin Klein Underwear."

The campaign will feature Calvin Klein Jeans Body Whitewash for men and women, the next extension in the more contoured, shape enhancing jeans that debuted for Fall 2009 (and looked like they were painted on Mendes' shapely derriere).

For spring 2010, the jeans will be "treated in clean, translucent washes and enriched surface treatments in shades of white, ozone, and cloud." This sounds suspiciously like '80s acid wash.

Ah, who cares?! We'll be too distracted looking at their greased-up bodies.

Mendes has previously been scantily-clad in campaigns for Calvin Klein Obsession and Calvin Klein Underwear.
