Even though we've always preferred Rachel Bilson, there's no denying Mischa Barton's natural beauty. Her gazelle-like frame, gaunt cheek bones, and saucer eyes, often soaked with sadness, lend her a redeeming quality that the Lohans and Hiltons of the world lack. That's why it pained us when the former Calvin Klein model resident of People magazine's "50 Most Beautiful People In The World" list dated several inductees into the greasebag hall of fame including Cisco Adler, Brandon Davis and The Kooks frontman Luke Pritchard. When paparazzi photos of a much plumper Barton surfaced recently, the reeling actress was forced to defend her physical transformation, citing dental work as the cause of her puffy face. Right, and dental work is why we have a beer gut too.
