Mischa Barton has denied reports she's joined the cast of TV show Gossip Girl, insisting she turned down the chance to do so.

Barton, best known for her role as Marissa Cooper on The O.C., claims she declined an offer to star as an old friend of Blake Lively's character Serena Van Der Woodsen on the show.

A spokesperson for Barton says, "She will not be on the show. She was approached, but her reps passed."

Mischa can't be bothered with her busy schedule of shopping and going to parties.

She can't let a little thing like an acting job get in the way of her acting career!
