The May 11 episode of Gossip Girl doubles as a pilot for a spin-off about young Lily van der Woodsen’s (Brittany Snow) raucous teen years in 1980s Los Angeles. But don’t go looking for her current flame, Rufus Humphrey, to pop up. “It’s not the story of how Lily met Rufus,” explains executive producer Josh Schwartz. In fact, he and co-creator Stephanie Savage are toying with the notion that Lily may have crossed paths with characters from their previous hit, which ended its run on Fox in 2007. The duo say they are discussing the idea of having teenage Lily interact with earlier versions of The O.C.‘s Kirsten Nichol and Jimmy Cooper. Our dream casting? Megan Fox as Julie Cooper!
