Glee creator Ryan Murphy has confirmed two more stars for Glee’s 100th episode airing in March.

Dianna Agron and Kristin Chenoweth will be a part of the series’ celebration, Murphy announced today. The two have appeared as Quinn and April on the musical dramedy, but neither have appeared regularly in recent story lines.

The two actresses join a growing group of Glee originals coming back to celebrate the 100-episode milestone which we suspect will shoot in the next month or two. Others Murphy has confirmed are Amber Riley (Mercedes), Mark Salling (Puck), Harry Shum Jr. (Mike), and Heather Morris (Brittany).

Murphy has insisted that “ALL” of the original cast members have been invited, so expect more surprises in the coming weeks. Glee Chat host Jack’s personal hope is for Dijon Talton will come back.

Cast members will be performing songs that fans voted for in a poll that ran on the Glee website. Gleeks could choose from a variety of songs, and the winners will be remixed and performed a second time at McKinley. “The episode will focus on McKinley High’s latest batch of seniors as they approach graduation and reminisce about their most memorable moments, while singing new versions of these iconic tracks,” says Fox.
