Eva Mendes: A Topless, Well-Oiled Jeans Machine!

Stop us if you've heard this before:

Eva Mendes and British model Jamie Dornan are appearing together in a sexy ad campaign for Calvin Klein.

This duo got oiled up and topless for a series of posters last year - and then decided they looked so nice, they'd do it twice!

Indeed, Mendes and Dornan are at it again, upping the racy ante with their latest set of photos. They're supposedly meant to help inspire shoppers to purchase jeans. But is anyone's focus really on Eva's bottom half below?
