Mischa Barton Arrested For DUI, Drug Possession

Spotted out just days ago smoking a joint in her car, it comes as little surprise that Mischa Barton was arrested in West Hollywood early Thursday morning for DUI.

According to Lieutenant Honings of the West Hollywood Sheriff's office, the former star of The O.C. "was stopped at 2:46 a.m. and arrested for driving under the influence of alcohol, possession of illegal narcotics and driving without a valid license."

"During Ms. Barton's detention, it was determined that she was an unlicensed driver and was driving while under the influence of an alcoholic beverage," police told press, adding, "Ms. Barton was arrested and transported to West Hollywood Sheriff's station where the booking process was completed without incident."

Barton was released after posting $10,000 dollar bond at around 10 a.m. and the investigation is still considered ongoing.

Joining a long list of celebrity DUI's this year, it'll be interesting to see how Mischa's latest troubles affect the release of her three upcoming films: St. Trinian's, Virgin Territory and Closing the Ring.
