New Year's Eve Miami 2007 - Kristin Cavallari Hosts New Years Party at Prive

Kristin Cavallari is making her ex, Brody Jenner, jealous while on her Miami vacation. The Laguna Beach babe has been splashing around with super hot Nick Zano. We hear they stayed holed up in their suite (complete with a bathtub fit for two) all day and then went skinny-dipping in the pool. Sources said Zano and Cavallari stopped by Nobu at the Shore Club for dinner, and were seated next to Jenner, who was dining with on-again couple Wilmer Valderrama and Mandy Moore. "Brody had that 'caught in the headlights' look," said a spy.
