Several years ago, Kristin Cavallari starred in the MTV "reality" show Laguna Beach. She then went on to do... well, not a whole lot, but she's still very good looking so we still remember who she is. Apparently realizing that she has no other discerable talents, she's set to replace Lauren Conrad as the main character on The Hills, which you may remember was a reality spin-off of Laguna Beach in the first place. Whatever, who cares, what matters is Kristin was photographed in the Caribbean recently wearing a tiny blue bikini and showing off her killer body.
