Kristin Cavallari's glass bikini: 'The glass sort of cut into my skin'

Kristin Cavallari may have left "Laguna Beach" behind, but she's still bikini-ready! The former reality show villain, who we just loved to hate on "The Hills," celebrated opening night of the Mercede Benz Fashion Week in Miami by walking the Diesel runway in a bikini made of glass.She was, understandably, nervous about wearing the cut-out swimsuit inspired by the color and material of a SKYY vodka bottle. "This is the first time I have ever walked a runway in a bathing suit," she tells People. "The glass sort of cut into my skin, and I was really nervous."
