The Stephanie Pratt PETA app has 'The Hills' star stripping it all off, save for a cute and cuddly bunny. The reality star gets naked for the animal rights group PETA to advertise an iPhone app that helps shoppers spend their money wisely.

The Stephanie Pratt PETA iPhone app, 'Be Nice to Bunnies,' will inform shoppers of the animal friendliness of the products they're buying. Now there's no excuse for having animal-tested beauty products in your shopping cart.

Implications - There are few ways more effective at drawing attention than featuring a naked celebrity in your ad, and PETA knows this. The laundry list of celebrities who have stripped down for the company is extensive and varied, including rapper Waka Flocka Flame, former Baywatch star Pamela Anderson, and now former 'Hills' star Stephanie Pratt.
