Swarovski Fashion Rocks charity fashion event wasn't hard. Why? "It's difficult to move in my shoes, because they are a size too small for me," said the singer who modeled and performed. "The wonderful lady who works for Donatella Versace let me wear her shoes. But I love them! Fashion is a personal choice. It's fun to dress up. But comfortable? These aren't comfortable shoes but they are fabulous. I'm most comfortable in boxer shorts and a tank top, but I don't think that would have worked on the runway!"
