PETA is known for its on-the-edge ad campaigns. But is this too far even for them? Italian actress and model Elisabetta Canalis went fully naked for a new PETA ad to draw attention to the plight of animals killed for fur or consumer products. "I think this is the best reason why I got naked in my life," she said. Here you may see exclusive footage of the photoshoot, courtesy PETA. The ad itself will appear this fall.
