Based on the best-selling series of young-adult novels by Cecily von Ziegesar and executive produced by Josh Schwartz (Chuck, The O.C.) and Stephanie Savage ( The O.C.), Gossip Girl is a one-hour drama based on the lives of privileged Manhattan prep school teens. The students first learn that Serena van der Woodsen, once the Upper East Side's most notorious party girl, is back in town the way they learn all the important news in their lives: from the blog of the all-knowing albeit ultra-secretive Gossip Girl. No one knows Gossip Girl's identity, but everyone in this exclusive and complicated vicious circle relies on her website and text messages for the latest scoop. Even Serena's closest friend, Blair Waldorf, is surprised to find that Serena has suddenly ended her self-imposed exile to boarding school and returned to Manhattan. Keeping track of the shifting friendships, jealousies and turmoil in this wealthy and complex world isn't easy, but it's what Gossip Girl does best
