What better way to get back at an ex-boyfriend than to strip naked and show him exactly what he’s missing out on! George Clooney’s ex Elisabetta Canalis is appearing in a new ad for PETA’s “I’d rather go naked than wear fur” campaign and looks smokin’ hot in her birthday suit. The Italian model, who was dumped by Clooney in June after two years together, is appearing on this season of ABC’s Dancing with the Stars.
