Sources confirm to me that Gossip Girl producers are actively planning to bring back Michelle Trachtenberg's delightfully wicked Georgina Sparks for another guest stint toward the end of this season.
The boss himself hints it's true: "It's safe to say you haven't seen the last of her," says executive producer Josh Schwartz, according to Nylon Online.
According to sources, this plot twist is still in the early planning stages—there's no deal or script done yet—but it is in the works for the last third of season two. - E! Online.
