St Trinian's star regrets "stupid" mistake

Mischa Barton has been discussing her pre-Christmas arrest and, unsurprisingly, she's not exactly proud of her behaviour.

According to the IMDB Barton told radio presenter Ryan Seacrest that: "I was pulled over and obviously, I'm 100 percent responsible for my actions in this case. I'm really disappointed in myself. I'm not perfect and I don't intend to do anything this stupid again."

Barton had been arrested on suspicion of DUI, and was booked for possession of narcotics and driving on a suspended license.
