Kristin Cavallari sunglasses jeans top the hills

First of all, I love Kristin Cavallari. From her flawless smile to her semi-bitchy antics on The Hills, this girl totally seems like the life of the party. However, it also seems like she's succumbing to the pressure to be as thin as a rail, because I'm seeing a whole lot less of her in these pictures!

Just don't lose anymore weight, 'kay?
