Olivia Munn has once again bared all for PETA. After posing in the nude for the animal rights group's "Boycott the Circus" campaign, the "Perfect Couples" actress stripped down to her birthday suit in two new "I'd Rather Go Naked Than Wear Fur" ads which tagline reads, "Who Needs Fur To Feel Beautiful?"

One of Munn's naked anti-fur ads, which was shot by Emily Shur and features a bunny, was unveiled on Beverly Blvd, in West Hollywood Thursday, January 12. Unfortunately, only a partial topless photo of the 31-year-old actress will appear on the Los Angeles billboard because the full-length nude version was deemed too risque, The Hollywood Reporter claimed.

Aside from appearing nude in the ads, Munn also filmed a video that highlights on Chinese fur farms. "When you think about even that little tiny trim of fur on your gloves or on your collar, that is still coming from an animal that had to endure so much pain just for you," she says. "There's nothing good about pretending like you don't know."

The actress who will next be seen in "Magic Mike" is the latest celebrity to participate in PETA's "I'd Rather Go Naked Than Wear Fur" campaign. She joined the likes of Khloe Kardashian, Taraji P. Henson and Elisabetta Canalis who have gone naked for the cause.
