#9: MISCHA BARTON

What to look forward to this year: It's hard to believe Barton went from the sexy, elusive, tan, and leggy Marissa Cooper on The O.C. to being Perez Hilton's degradingly-named "Mushy Fartone." Since she left the generation-defining show, she's put on some weight, suffered through a cancelled TV show (The Beautiful Life), starred in straight-to-DVD movies, had multiple run-ins with the cops for her pot and alcohol problems, and was treated for depression. But, this year, her reps are allegedly reporting that she's vying for a spot on the always career-boosting Dancing With The Stars. Also, her t.A.T.u-centric Russian film You and I, filmed with Shantel VanSanten years ago, is finally set to make its theatrical debut.
