Mischa Barton and Audrina Patridge showed up to the Fire and Ice Gala Benefiting Fresh2o at Hollywood's Lexington Social House on Thursday wearing similar outfits. Who looked better?

The gala benefited Fresh2o, an organization that helps provide clean water and sanitation to poverty-stricken areas around the world in order to combat water-related illnesses, which, believe it or not, kill more people annually than anything else.

Poor Kristen Stewart. She had to deal with a cheating scandal last summer, and now this! The actress has topped a U.K. poll to find the "Least Sexy Hollywood Actress." Ouch!

Obviously, those surveyed rated sexiness as more than just a physical attribute because Stewart is definitely not a bad looking woman. Perhaps her on/off relationship with British heartthrob Robert Pattinson had something to do with it?

Other unattractive ladies on the list include former "Sexy and the City" star Sarah Jessica Parker and troubled actress Lindsay Lohan.
