GLEE Approaches 500th Musical Performance

After four seasons and many, many milestones, Glee is prepping to hit another major mark in its history.

Fox's musical comedy is set to air its 500th musical performance this season - perhaps a little sooner than expected.

The folks over at Carter.com predict that the milestone performance might air during Will Schuester and Emma Pillsbury's wedding in March. As of now, no details on what the 500th song might be have been released.

Darren Criss corroborated the big news, tweeting this week: @DarrenCriss "I get to shoot two great songs today-the 1st is from one of my favorite movies, and the 2nd will be our 500th musical number on Glee. 500th!"

He later went on to post: "The episode we're shooting right now is a shining example of what 'movie magic' really is. I've been in awe all week. Can't wait til it airs"

Glee is a musical comedy about a group of eager and ambitious students who strive to outshine their singing competition to win Nationals while navigating the cruel halls of McKinley High.
