Glee's 100th episode will air next March, but it will feel like it's April.

The familiar faces keep lining up to appear on Glee's sure-to-be-epic upcoming 100th episode, which will air March 18, 2014. And you can now add one more to the list: Kristin Chenoweth, who plays Schue's old pal April Rhodes!

Ryan Murphy took to Twitter on December 4 to announce the happy news:

Yay! We loved seeing April over the years on Glee as she pursued her dream of launching that all-white production of The Wiz, so it will be great to catch up with her now. Is she still spending her free time at Rinky Dinks? We shall see.

April is one of numerous long-missing characters who will return for the episode, including Brittany (Heather Morris), who hasn't been on the show since the Season 4 finale, and Quinn (Dianna Agron), who's been gone even longer than Brit. 

And in more news that is sure to delight most longtime Glee fans, a source tells E! Online that the majority of the episode's songs will be performed by the original glee members. "Most of the songs will be sung by the Originals, with special guest stars as well," says the source. "The Old New Directions."

But which songs will be performed? Well, that's up to you, as Glee fans have been voting on their ten favorite Glee songs, which will then be redone for the episode. Sadly, voting has closed.

Are you excited to see April on the show again? Or are there other guest stars that you'd rather see return for the episode, like Gwyneth Paltrow (Holly Holliday), Neil Patrick Harris (Bryan Ryan), or Matt Bomer (Cooper Anderson)?
