'Glee's Dianna Agron Decides Whether or not to come Back for Show's 100th Episode

Good news, Gleeks: According to creator Ryan Murphy, Dianna Agron is officially in for Glee 's 100th episode. Murphy revealed the news in a tweet today, saying, "Dianna is IN for Glee 100th!" News of Agron's appearance comes shortly after it was announced that former regular cast members Amber Riley — who you may have seen WINNING Dancing With the Stars recently — Mark Salling, Heather Morris, and Harry Shum Jr. are also set to return for the show's 100th. As previously reported, Murphy has invited all of the show's original cast members to return for the episode, so if it all ends up working it, we could be looking at a very classic Glee episode here. At the very least, a nice throwback to a classic Glee episode.

But, hey: That's not all the good news. According to Hypable , Kristin Chenoweth — who has previously appeared in three Glee episodes — is set to return to the show as April Rhodes for the episode as well. Dianna, Kristin, Amber, Mark? Just make sure Heather Morris spends (most of) her screentime making out with Santana, and we have got ourselves a very promising 100th episode.

Glee's 100th episode is set to air on Fox on March 18 of next year.
