The misdemeanor charges stem from the former O.C. star's arrest in December
Mischa Barton has been charged with driving under the influence and possession of marijuana, stemming from her arrest in December, prosecutors announced Tuesday.
The former star of The O.C. was also charged with driving without a valid license. Her arraignment on the misdemeanor charges is set for Thursday in Beverly Hills Superior Court.
Barton, 22, was arrested for investigation of DUI in West Hollywood on Dec. 27 after her vehicle was seen straddling two lanes of traffic and she failed to signal when making a turn, police have said.
