>Olivia Munn, who appeared in “Iron Man 2′ and works for Jon Stewart’s comedy show, is giving up her clothes to protest the use of fur on behalf of animal rights group PETA. She poses topless with a bunny to get her point across. Really!

Munn, who has long been an animal rights activist, posed for celebrity photographer Emily Shur. The resulting ad appeared today (Jan. 12) on a billboard on Beverly Blvd. in Los Angeles. That is, most of the ad.

The PETA poster was cropped around Munn’s shoulders to avoid any suggestion of nudity. Actually, she artfully covers her private parts with her leg and arm, so nothing really shows. In a video accompanying the ad, Munn, 31, explained her feelings about animals.

PETA, short for People for the Ethical Treatment of Animals, has enlisted a number of celebrities to pose in semi-nude ad campaigns to draw attention to the plight of animals used as food and for other commercial purposes.

If butchering farm animals and exotic species isn’t bad enough, the group claims that dogs and cats are routinely slaughtered and their fur is misrepresented in all kinds of products, from toys to fur coats.

“When people learn that… furriers intentionally mislabel the fur of cats and dogs as fur from other species or as faux fur — then every decent human being will want to go fur-free,” the group says on its Web site.

Munn is no stranger to PETA. She posed for the group in 2010 to call attention to the plight of circus elephants. She helped PETA publicize the plight of a sick elephant with a touring circus last year. The elephant was ultimately pulled from the show.

The video contains some graphic images of animals being beaten to death with clubs. “It’s never ok and it saddens me that it happens in the world,” Munn says. “When it comes to feeling fear and pain and loniness, we’re all the same.”
