Who Is Gossip Girl? The Final Reveal Explained (S6 E10)

Spoiler warning: this page names Gossip Girl. If you are mid-rewatch, stop here.

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 reveal, step by step

After six years of anonymous posts, the finale drops the mask in the middle of a wedding-season sprint through Manhattan. Dan admits the blog was his, the group reacts in real time, and the episode jumps forward to show what the reveal cost each of them and where they end up.

Why it's 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 instead. His own storylines are written as a way in, which is why the earliest posts target his sister and himself hardest of all.

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 had.
• Dan's published fiction repeatedly recycles the same events the blog broke first.

What the reveal actually changes

The finale doesn't just name the author — it reframes six seasons of surveillance as one outsider's attempt to be let into the world he was writing about. Every character's reaction in the last episode is really a verdict on whether that motive forgives the damage.

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.
