Yes, Kristin Cavallari was in the last season finale of the Hills. She doesn't like Lauren at all. And back in the day, they use to attend high school together. They were both on a show called Laguna Beach!! It was based around 6-8 close friends and their enemies. And you see, Lauren always like Stephen, Kristin's on again off again boyfriend. And there were points in which Lauren and Stephen would hook up. Because they've known each other all their lives. So when Lauren decided to leave the Hills, they brought in Kristin. She's known for her b****y attitude and she doesn't give a F*** about anyone else's feelings! She's totally awesome!! =] I suggest that you watch this show!!
big fan of the hills...Kristen and everyone else!!
