When Naomi Campbell is a no-show to walk the runway for your swimsuit collection, who ya gonna call? Apparently, only a male model will do. So stunning Brazilian Rodrigo Rothen filled in for the temperamental Brit at the Rosa Cha swimsuit show in Sao Paolo the other night. A witness reported to Page Six that he "strolled out in a Speedo and then stripped down naked under a shower on the catwalk," leaving the socialites in the audience requiring smelling salts. Fortunately, there's video to back up the story.
