"Gossip Girl" ended its six-season run with a major reveal: The identity of its tattle-tale blogger.

Known only as Gossip Girl and given narrative voice by actress Kristen Bell, she turned out to be a he. The Monday night finale revealed Gossip Girl was secretly the work of character Dan Humphrey.

Dan, played by Penn Badgley, was a budding poet and a student at Manhattan's posh St. Jude's Preparatory School for Boys. But he came from the other side of the tracks, or rather, from Brooklyn, across the East River.

His Gossip Girl blog was a sassy tell-all account of the lives of the privileged young adults who made up the CW drama. Other series stars included Blake Lively, Leighton Meester and Chace Crawford.

At the end, Dan fittingly pronounced Gossip Girl dead.
