Oliva Munn has boldly gone where she's once been before: naked, on a billboard, for PETA.
The actress, who stripped down for a second time in support of animals, revealed her latest campaign against animal cruelty yesterday at a ceremony in Los Angeles. Munn first posed nude for PETA in 2010 and called for a boycott against the circus. Her latest campaign asks, "Who needs fur to feel beautiful?"
"Please don't wear fur," Munn Tweeted
when the anti-fur poster was unveiled. "Even a tiny bit of fur trim caused an animal extreme suffering & took a life."
