blair waldorf gossip girl finale cw 'Gossip Girl' sneak peek: Blair's diary could be her undoingWith the Gossip Girl computer returned to its rightful owner, chaos is about to rain down on the Upper East Side. And the first victim of this new order appears to be Queen B herself, Blair Waldorf (Leighton Meester).

In a preview clip of the “Gossip Girl” season finale, we learn that, due to Serena’s carelessness, pages of Blair’s diary have been acquired by the gossip maven. Once these pages are posted online, this immediately wreaks havoc for Blair, not only in her relationship with Serena (Blake Lively) but with her new love Dan (Penn Badgley).

Uh oh. Uh oh.
