Just days after being released from an LA hospital, where she had been placed in an involuntary psychiatric hold for a week, Mischa Barton boarded a plane for the east coast. The former O.C. star flew to New York City to begin filming her new TV show, The Beautiful Life. The troubled actress has been cast to play Sonja Stone, a model hooked on pills. Shooting on the CW series, created by Ashton Kutcher, is reportedly set to begin on July 31.
