Kristin Cavallari Gets Confused by the Cameras

Kristin Cavallari enjoyed a girls night out last night in West Hollywood. The Hills starlet waved her hands in the air, giving the "I don't know" gesture to photogs. Wonder what Kristin was confused about? Maybe whether or not Spencer Pratt will be leaving The Hills for good?

Kristin has been busy filming! What a hard job she has.

She rocked a short black mini dress for her night out on the town. Fellow starlet, Audrina Patridge, was also out, but avoided the paps.
