Mischa Barton leaving the Ivy restaurant. Los Angeles, California - 11.02.08

The Los Angeles District Attorney announced the news on Tuesday (26Feb08).

Barton was pulled over by traffic cops after they reportedly spotted the vehicle she was driving "straddling two lanes of traffic". The police report also suggests the actress failed to signal when making a turn.

Police determined the former The O.C. star was driving without a valid license and under the influence of alcohol.

She was released on bail and has since apologised for her actions.

She stated she was wrong to attempt to drive home after partying with pals.

The 21-year-old has confessed she didn't have a driving license because she rarely gets behind the wheel.

She said, "I'm really disappointed in myself. I'm not perfect and I don't intend to do anything this stupid again."
