Gossip Girl is unmasked in the series finale, "New York, I Love You XOXO" — Season 6, Episode 10, the last episode of the show. The person behind the blast is Dan Humphrey, the Brooklyn outsider who spent six seasons writing about the world he wanted to join.
The episode, in one line
After six years of anonymous posts, the finale drops the mask in the middle of a wedding-season sprint through Manhattan, then jumps forward to show what the reveal cost and what it changed for everyone involved.
Why Dan Humphrey
The show frames Dan's authorship as the ultimate act of an ambitious writer: he could not get inside the Upper East Side, so he narrated it. His own storylines are written as a way in, which is why the earliest posts target his sister and himself hardest.
The clues that were there all along
- Dan is the only main character Gossip Girl rarely damages in a way he cannot recover from.
- The first blast announces Serena's return — news a Brooklyn observer at Grand Central could plausibly have.
- Dan's published fiction repeatedly recycles the same events the blog broke first.
How fans reacted
The reveal split the audience immediately. Some read it as the only ending that made thematic sense; others felt the timeline never quite added up. More than a decade later it remains one of the most argued-about finales in teen drama, which is part of why the show keeps finding new viewers.
Where the finale was filmed
The last season leans on the same New York landmarks the series made famous: the Met Steps on Fifth Avenue, the Empire Hotel near Lincoln Center, Central Park and the Upper East Side blocks around them. They are all still standing and all still photogenic.
