Pratt is the new face for PETA's "Be Nice to Bunnies" cruelty-free iPhone shopping app, which encourages consumers never to buy personal-care and household products that were smeared into rabbits' eyes or force-fed to mice or guinea pigs.

The starlet's ad was deemed "to risque" for Apple's iTunes Store, so PETA will be using a clothed image of Pratt for the app's cover.
