Great news today for those who didn't stop believing in Glee: Fox has renewed the musical comedy for Season 5... and 6!

The unexpected news come after a season in which ratings have slipped, although buzz surrounding the series remains strong. It aired its 500th performance last month.

Said Kevin Reilly, Chairman of Entertainment, Fox Broadcasting Company, upon making the announcement:

“Glee debuted as the first and only successful musical comedy series on television, and more than four years later, it continues to defy genres, break new ground and have a significant impact on popular culture. Week in and week out, Ryan Murphy, Brad Falchuk, Ian Brennan, Dante DiLoreto and the entire Glee team deliver a series that not only delights and surprises fans, but also inspires them to talk about, share, debate and engage with the show – and I’m absolutely thrilled to have them on board for another two seasons.”

Three more episodes remain in Glee Season 4, with spoilers revealing that Blaine will propose to Kurt on the finale.
