Gossip Girl

Hit TV drama Gossip Girl's upcoming sixth season will be its last.

The teen show, based on author Cecily von Ziegesar's book series of the same name, debuted in the U.S. in 2007 and quickly became a global phenomenon, making stars of its lead cast members Blake Lively, Leighton Meester, Chace Crawford, Ed Westwick and Penn Badgley.

But executives at The CW network, where the drama airs in America, haveannounced the program will draw to a close after a shortened 11-episode sixth season hits screens this autumn (12).

In a statement to UsMagazine.com, show bosses reveal the final storyline will revolve around an unstable Serena van der Woodsen, the New York socialite played by Lively "Serena has gone off the grid, beyond even the reach of Gossip Girl.

"Her friends fear for the worst and hope for the best, but even they can't imagine where they will ultimately find her".
