Leighton Meester: 'Gossip Girl' Is Not Who I Thought It Was (VIDEO)

Leighton Meester knows the identity of "Gossip Girl," but that's one secret she'll never tell.

Meester stopped by "The Talk" to promote her new flick, "The Oranges," and the final season of the CW series and she called the final 10-episode season a "perfect wrap-up."

Fans and cast members alike have wondered about the real identity of the mysterious titular blogger for six seasons and it will finally be revealed when the show comes to an end. "I just read it, so I know," Meester said on "The Talk." "It's not who I thought it was, though."

This season fans can expect a lot of "back and forth" between Meester's character, Blair, and Chuck (Ed Westwick).

Check out the video below for more.

"Gossip Girl" Season 6 premieres on Mon., Oct. 8 at 9 p.m. ET on The CW.
