Mischa's Got Class

Maybe getting written out of "The O.C." was a hint?

Mischa Barton's character on the FOX series was killed off in the season finale and she's using her newfound time off to brush up on those acting chops.

Taking a break from the LA and NY club scene, the underage thespian has enrolled in acting classes at London's Royal Academy of Dramatic Art.

With four feature films coming out, it looks like Barton realized not all her roles would be as easy - and as true to life - as playing a spoiled California teen.
