Elisabetta Canalis And Other Stars Go Naked For PETA

People for the Ethical Treatment of Animals (PETA), the organization known for its racy and often disturbing attention-grabbing tactics, has long been a go-to cause for celebrities with a philanthropic itch to scratch. Recently, some stars have gone the extra mile to bring the issue of animal rights front and center — by showing a little skin of their own. Former Dancing with the Stars contestant and Italian model Elisabetta Canalis, who dated George Clooney for two years, unveiled her revealing ad in September, adding her name to a list of celebs including Eva Mendes and Khloe Kardashian.

Canalis stripped down to help spread the word about the cruelty involved in fur. "I decided to go nude because I think that nudity always creates a big reaction," she explain on PETA's web site. "That is what is required to keep people's attention on such a brutal practice. These poor animals are electrocuted, skinned alive, drowned, and bludgeoned just for the sake of fashion."

Canalis is not the first reality starlet to drop trow for PETA. Bethenny Frankel of the Real Housewives of New York unveiled her "Fur? I'd Rather Go Naked" billboard in New York City in 2009. Frankel, 39 at the time, faced criticism that her picture looked too good to be real and in response released an un-air-brushed version of the photo to UsMagazine.com.

"Everything I'm about is being honest and being upfront," Frankel said. "So if people are talking and saying [the photo] was airbrushed...then, you know what? Here's the picture. Have it your way."
