Let's be honest: Laguna Beach and The Hills just wouldn't have been the same without Kristin Cavallari's realness. From the very beginning, Kristin had absolutely no problem being totally, brutally honest, and her hysterical facial expressions said it all. She was the queen of one-liners — "What happens in Cabo stays in Cabo" — and nobody did a better eye roll. Period. Last month, Kristin got candid about Laguna Beach, saying she "felt very used and manipulated," and more than once, she's hinted that much of the drama wasn't exactly "real." In any case, to celebrate Kristin's 28th birthday, take a look at where the casts of Laguna Beach and The Hills are now, and then check out all the times Kristin was perfectly, hilariously unapologetic.
