As the "Glee" 100th episode looms ever closer, more spoilers are surfacing regarding a few potential returning cast members.

So far, the "Glee" 100th episode will attract some very memorable original cast members, including Harry Shum Jr., Heather Morris, Mark Salling, Amber Riley, and Dianna Agron.

In addition, spoilers confirm that the "Glee" 100th episode will also feature the return of Kristin Chenoweth as April Rhodes.

However, one cast member who will not be returning to the "Glee" 100th episode is Jessalyn Gilsig, who played Terri Scheuster during the early seasons of "Glee."

According to TVLine, currently the actress is not planned to return for the 100th episode, particularly since Gilsig won't be able to contribute musically to the episode in any way.

Another cast member who has not been confirmed to return for the "Glee" 100th episode is Jayma Mays as Emma Pillsbury.

Given her work on "The Millers," it seems unlikely that Mays will be able to return for the special event, but fingers crossed nonetheless.

It's unclear whether Mays has the desire to return to "Glee" for another go, but one show she wants to return to before the end is "How I Met Your Mother."

"I would love to go back, but I haven't been told that I'm coming back as of yet," she shared, according to Digital Spy.
