She’s always up for a good time and Kristin Cavallari was spotted hamming it up at the Breeders’ Cup Winners Circle event at the ESPN Zone and LA Live last night (November 5).

The “Laguna Beach” babe looked lovely as she posed for the paparazzi in a sexy black semi-see-through top with black trousers and beige heels.

From there, Kristin satisfied her appetite for nightlife with a trip to the hottest new club in West Hollywood, club Voyeur.

Earlier in the day, Miss Cavallari was spotted hard at work, filming new scenes for “The Hills” with Stacie Hall in Malibu.
