Did you figure it out?
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).
