The early success of The O.C. got us ready to O.D. on the Q.T. that is Mischa Barton—and we sure had to wait long enough for her part-ons to be barely legal. Mischa wasn't the kind of gal we'd want under our bed in The Sixth Sense (1999), and not just because she was a walking corpse. She was also way too young to be in our love dens. The luscious London-born lassie did her duty on the sidelines in Lost and Delirious (2001), arranging the lesbian liaisons between Piper Perabo and Jessica Paré, and she bared a groin-tinglingly smooth swath of midriff alongside Bijou Phillips in Pulse (2003). Perhaps Bijou's bad-gal ways rubbed off on Mischa, since her next outing was in the orgasm-centric The OH in Ohio (2006), where Mischa provided titillation with some pastied peaks and panty-clad posterior. But it was her next film, Closing the Ring (2007), that finally brought out Mischa’s mams—and earned the honor of being named the top nude scene of 2008 by Mr. Skin. She followed that up with a bathtub boob scrub in Assassination of a High School President (2008), though we're still waiting for Mischa to reveal her ballot box.
