"Dianna [Agron] is IN for Glee 100th!" Creator Ryan Murphy revealed the news on Twitter after telling fans that "ALL" the original "Glee" cast members had received invitations to appear in the special 100th episode of the show, E! News reports. 

Gleeks were concerned that Agron, who played Quinn Fabray, might not make an appearance because she wasn't in the tribute special for the late Cory Monteith. There were rumors that the 27-year-old actress was not asked back for the "Farewell to Finn" episode because the other cast members didn't like her.

A source told Radar Online that Lea Michele (Rachel Berry) and Murphy "intensely dislike Dianna and have both worked to marginalize her as much as possible." On the show Agron's character was Finn's girlfriend and was kicked off the cheerleading squad after she became pregnant with (presumably) Finn's baby.

She ended up giving birth to a girl named Beth but gave the baby up for adoption. Both Murphy and Agron shot down the rumors.

"I've got nothing but love for that show and everybody involved in it, and it was such a huge part of my life. I think it's equally hard when I'm not there every day anymore, I don't see all of them every day anymore to have things like this flying around," she told The Irish Independent in November. "It's more heartbreaking than it would be if I was there with everybody. It makes me feel even farther away from our show."

The last time Quinn made an appearance on "Glee" was for Will (Matthew Morrison) and Emma's (Jayma Mays) wedding, where she and Santana (Naya Rivera) hooked up. We wonder what Quinn will be up to for the 100th episode?

Coming back for the special episode so far is Amber Riley, Mark Salling, Harry Shum Jr., Kristin Chenoweth and Heather Morris.

"Going to be fun... #glee100," Agron tweeted.
