Audrina Laughing at Kristin Cavallari!

The Hills stars Kristin Cavallari and Audrina are still involved in a cat fight! Kristin seems to have a bad habit of going after Audrina's ex flings! First it was Justin Bobby and now its Tal Cooperman! Audrina's comments on Kristin's escapades with her left overs? "Its laughable" she says! There must be a serious lack of hot men in Los Angeles if Kristin only has Audrina's exes to go for, or is she trying to replace Audrina's role on The Hills too! We think its a bit weird either way!
