Kristin Cavallari the hills shirt sunglasses

We caught Kristin Cavallari and some pals lunching in Beverly Hills yesterday afternoon, and when asked about co-star Stephanie Pratt's DUI, Kristin informed us that it was the first she had heard about it! Kristin added that she didn't hang out with Stephanie all that often, so she couldn't comment about her love for booze, but we definitely have the pix to prove it!
