Mischa Barton
Mischa Barton rose to prominence in the early 2000s, despite having begun acting in the 1990s. She is well recognized for her role as Marissa Cooper on The O.C. She was also something of a fashion icon at the time. However, as her prominence and influence diminished, she began to party hard and was even thought to have substance addiction difficulties, which dramatically affected her current appearance.
