LOS ANGELES: The Fox TV series ''Glee'' will keep on singing for another two years.    

The network announced on Friday that it has renewed the show about music-loving students through 2014-2015 - its 6th season.

In a statement, Fox Entertainment Chairman Kevin Reilly said ''Glee'' continues to break new ground as a rare successful TV musical comedy. The show has been a music hit as well, with more than 50 million downloads of ''Glee'' tracks and worldwide album sales of more than 13 million.

''Glee'' has expanded from its original focus on the McKinley High School glee club to the college world of Rachel and Kurt, played by cast members Lea Michele and Chris Colfer.

Next Thursday's episode will feature Sarah Jessica Parker. Gwyneth Paltrow and Kate Hudson are among previous ''Glee'' A-list drop-ins.
