The series finale of Gossip Girl, which aired Monday on the CW, had it all: two weddings (Blair marries Chuck; Serena marries Dan), two stunning wedding gowns (powder blue, beaded Elie Saab Couture on B, and a gold and white strapless Georges Chakra Couture on S), cameo appearances by New York City Mayor Michael Bloomberg, Rachel Bilson and Kristen Bell (as themselves, reading the roles of Blair and Serena from a script written by Dan), the return of Jenny Humphrey (briefly!) and the reveal of Gossip Girl’s identity. And it’s not Dorota. The person behind the mysterious blog that has kept tabs on the Upper East Side’s elite was not a girl at all – it was Brooklyn’s very own Dan Humphrey (Penn Badgley). Gossip Girl‘s Costume Designer Recalls His Favorite Fashion Moments Dropping Bell’s trademark voice, the real Gossip Girl explained in a typical, if more masculine, voiceover: “The Upper East Side was like something from Fitzgerald or Thackeray – teenagers acting like adults, adults acting like teenagers, guarding secrets, spreading gossip all with the trappings of truly opulent wealth. And membership into this community was so elite you couldn’t even buy your way in. It was a birthright – a birthright that I didn’t have. And my greatest achievements would never earn it. “All I had to compare it to was what I read in books. But that gave me the idea: I wasn’t born into this world … maybe I could write myself into it. I overheard enough conversations to mimic the voice of the Constance girls, but every writer needs his muse and it wasn’t until that photo of Serena in the white dress that I knew I had something strong enough to actually create a legend and launch a website. “Within weeks I was getting dozens of emails with stories about Upper East Siders, so I posted them anonymously. And then I got more. Before long it was a monster. Everyone was sending tips … When Serena came back from boarding school, I wrote my first post about me, Lonely Boy, the outsider, the underdog. I might have been a joke but at least people were talking about me.” How did the others react? With shock and disbelief. Dorota asked for vodka. “Gossip Girl ruined our lives,” Blair (Leighton Meester) said. “He schemed and lied and spread horrible stories.” But Serena (Blake Lively) found acceptance: “What he did was … write a love letter,” she said. “And not just to me, to all of us. It made me realize that I don’t want to run away, that you guys are my family. I belong here. And so does Dan.” “I guess that means it’s all over now,” Blair said. “That we can all grow up and move on.” “Yeah,” added Dan, “Gossip Girl’s dead.” Xo, xo!
