In the stunning shot, Canalis, 32, shows off her flawless figure for PETA's famous "I'd Rather Go Naked Than Wear Fur" campaign.
"I decided to go nude because I think that nudity always creates a big reaction," said Canalis, who split with George Clooney over the summer. "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."
Meanwhile, as Canalis mends from her Clooney split, she's keeping busy -- and in incredible shape -- with rigorous DWTS training. "I have a very strict teacher," she told Italy's Chi magazine. "We practice for six hours a day!"
