Kristin Cavallari the hills dress heels purse

Last night Kristin Cavallari dined at Boa, and the Hills hottie reminded us once again that she's the sexiest b*tch on the block.

Sure, Lauren Conrad is cute and all, but Kristin's always been the more attractive of the two, right? Plus, she has the WAY more attractive personality...she's always so bubbly and outgoing, we'd much rather hang out with her!
