The mature 11-year-old actress joined the star-studded casts of The Sixth Sense and Notting Hill.
Even when she was a child, 26-year-old Mischa Barton's beauty was undeniable. Modeling for Calvin Klein at age 11, she kicked off a career as an advertiser's darling, appearing in campaigns for Neutrogena, Bebe and Keds. From 2003 to 2006, she further secured her pop-culture presence as Marissa Cooper on The O.C. Now, after several forays into movies, she's back in the public eye with clothing and bag lines.So what's the secret to her life-long allure? According to her makeup artist, Nick Barose, it's her natural glamour. "She doesn't like a typical Hollywood look with fake lashes and bronzer." Instead, she goes for '60s-inspired styles like dramatic cat-eye shadows and nude lips combined "with a small element of fun," like rocker chick black polish. "In 50 years, she will still look timeless," says Barose. Especially if her first decade is any indication.
