The usual fare turned up at the swanky AIDS Life Ball in Vienna on Saturday: Pamela Anderson, mermaids, transvestites, and lots and lots of glitter. Then came a more unexpected addition: Bill Clinton. The former President joined celebrities and designers for the launch of the annual AIDS fundraiser, which featured a Water, Earth, Air and Fire fashion show. The Water segment of the show featured some crazy costumes and models, including singer Katy Perry dressed as a seashell. Just another one of Bill’s foreign trips.
