Leighton Meester is back in the spotlight — and so is Blair Waldorf. The actress, best known for playing the sharp-tongued queen of the Upper East Side in the original Gossip Girl series, recently sat down with Screen Rant at SXSW to discuss her new film Basic. But the conversation quickly turned to something that has fans buzzing: a new book dedicated entirely to the character that made Meester a household name.
For a generation of viewers who grew up watching Blair Waldorf scheme, style, and occasionally soften her way through six seasons of television, the news of a Blair-focused book feels like more than a publishing announcement. It feels like a cultural moment.
What We Know About the New Blair Waldorf Book
Details about the new Gossip Girl book remain limited, but what is confirmed is notable: the book is dedicated to the character of Blair Waldorf, and Leighton Meester — the actress who portrayed Blair across the original series — has already weighed in on it.
Meester spoke about the book during a Screen Rant interview at SXSW, where she was primarily promoting her role in the new film Basic, which also stars Ashley Park and Taylor John Smith. The fact that she addressed the Blair Waldorf book at all — at a major film festival, while promoting an entirely different project — says something about how significant the news feels, even to the people who lived it.
The original Gossip Girl series ran from 2007 to 2012 and starred a cast that has since become genuinely iconic: Blake Lively, Penn Badgley, Ed Westwick, Chace Crawford, Leighton Meester, Taylor Momsen, and the late Michelle Trachtenberg. It has long since crossed from popular teen drama into full-blown cult classic territory.
Why Gossip Girl Still Has This Kind of Pull
The timing of this book announcement is not accidental. Since the original series landed on major streaming platforms, it found an entirely new audience — younger viewers discovering it for the first time alongside original fans returning for the nostalgia. That second wave of popularity reignited interest in the characters, the fashion, and the world of the Upper East Side in a way that few shows from that era have managed.
Blair Waldorf, in particular, has taken on a life of her own in popular culture. She is quoted, cosplayed, and referenced constantly — a character who somehow feels as relevant now as she did when the show first aired. A book built around her is the kind of project that speaks directly to that ongoing obsession.

Meester at SXSW: Two Big Stories at Once
Leighton Meester’s appearance at SXSW was primarily tied to Basic, a new film in which she stars alongside Ashley Park and Taylor John Smith. The festival interview, conducted by Screen Rant’s Ash Crossan, covered her work on that project — but the Blair Waldorf book news clearly overshadowed part of the conversation.
That kind of overlap is telling. No matter how much time passes or how many new projects Meester takes on, Blair Waldorf remains a defining part of how audiences see her. The book news arriving at the same moment as a new film launch only amplifies both stories.
What Happens Next
The specific content of Meester’s reaction to the new book, along with further details about the book itself — its author, publisher, release date, and format — have not been confirmed in the available source material at the time of writing.
What is clear is that the Gossip Girl universe shows no signs of fading. Between streaming revivals, cast members remaining in the public eye, and now a new book centered on one of its most beloved characters, the Upper East Side still has plenty of story left to tell.
For fans who have followed Blair Waldorf from her first headband to her last scheming monologue, a dedicated book feels less like a surprise and more like something that was always inevitable.
