Mischa Barton won't be joining the cast of CW's Gossip Girl.TV Guide reported that Barton, 22, had been approached to play Georgina Sparks, an old friend of reformed party girl Serena van der Woodsen (Blake Lively). But her rep says, "She will not be on the show. She was approached, but her reps passed."

The actress " who was charged with DUI and marijuana possession this past week from a December arrest " last appeared on the Fox hit The O.C. Her character was killed off in 2006.

You know what? I can't blame Mischa for turning the offer down. She was already on a teen show when she was a teen. It's time for her to grow up, branch out and jumpstart her future porn career.
