Heidi Montag

When Lauren Conrad first arrived in L.A. from Laguna Beach, Heidi Montag (pictured left in 2006, and right in April 2010) was her roommate, best friend and partner in crime. But when Heidi started dating the biggest creep in California, Spencer Pratt, their friendship took a hit. And when Heidi stood by her man -- after he started rumors about Lauren appearing in a sex tape -- Lauren had had enough. As she so eloquently said to Heidi one drunken night out: "I want to forgive you, and I want to forget you." Now, Mrs. Pratt is virtually unrecognizable after indulging in a plastic surgery marathon, appearing in a Jennifer Aniston movie, pursuing her pop star aspirations, and generally offending the world with her inane twittering.
