Actress Kristen Bell, the narrator of the series during all seasons makes a cameo as herself (but is not revealed as Gossip Girl). Several former Gossip Girl cast members appear in the finale, including Jessica Szohr, who played Vanessa Abrams, and Katie Cassidy, who played Juliet Sharp. Former series regulars Connor Paolo (Eric van der Woodsen) and Taylor Momsen (Jenny Humphrey), each appear also with one line a piece. Blair Waldorf (Leighton Meester) and Chuck Bass (Ed Westwick) get married. In the final moments the series speeds forward five years later where Chuck and Blair are revealed to have had a child and Nate Archibald appears successful and is rumored to be running for Mayor of New York. The show ends with the wedding of Serena van der Woodsen and Dan Humphrey. It's a small ceremony, in what looks like Blair and Chuck's home together, where Lily is with her original husband William, Serena and Eric's father, and Rufus seems to be happy with another woman (musician Lisa Loeb, who guest-starred in the first season) along with Dorota, Nate, Jack Bass and Georgina (who are now together), Jenny and Eric. During the finale, it was revealed that Dan Humphrey was Gossip Girl.
The night was kicked off with a look back at the show’s six-year run (featuring clips and interviews with the cast and producers), followed immediately by the final episode, which TVLine can exclusively reveal is titled, “New York, I Love You XOXOX.”
