Eva Mendes backseat photoshoot vampEva Mendes was working her sexiest poses while sitting in the backseat of a Chevelle yesterday wearing Amy Winehouse-inspired eyeliner.

The model slash actress is no stranger to striking a pouty pose -- in addition to appearing naked for PeTA, she's been sizzling in a series of Calvin Klein ads!

These outtakes are pretty racy... can't wait to see the finished product!
