Eva Mendes says she's got no problem stripping down to her skivvies and beyond -- as long as it's all for the sake of her "art."

Well, her "art" and PETA ... and Calvin Klein!

“I’ve never had a problem with nudity, but I don’t put it out there without a reason. I’m not an exhibitionist. But, honestly, for my art I’ll do anything almost. I’ll go there,” she says in the new issue of W Magazine.

Posing in a sexy Louis Vuitton silk and cashmere velvet corset and skirt, Eva also says that she doesn't consider herself a Latina actress, but an American actress.

"I don’t consider myself a Latin American actress. I was born and raised here, and I have Cuban parents, but for me, I am the new American girl. It’s not only Drew Barrymore and the blond Mid-western girl. This, [pointing to her face] is also what we look like now,” she said.

Beauty AND brains? Loves it!
