The Italian designer recently chatted with Vogue U.K. and spurted out classic Cavalli gems about both the duchess ("A princess should be sexy") and Victoria Beckham ("I remember when she asked me to design the Spice Girls costumes for the reunion in 2008, I was so surprised and pleased because I really didn't like the competition — Dolce & Gabbana"). More surprisingly, he also shared a silly tidbit about himself that involved a used cigarette and the Internet. "At the Cavalli for H&M launch in 2007, I stepped out of the car smoking and dropped my cigarette on the pavement — a disgusting, dirty Italian habit — and I found out not long afterwards that it was sold on eBay for £250," he said. "My children said to me, 'You are not allowed to throw your butts away ever again, we'll have them.'" Somebody spent nearly $400 for something that touched Cavalli's mouth! That person could have purchased a new, animal-print wallet instead.
