What would a show about singing be without an appearance by actress Kristin Chenoweth?!?

Fortunately, Glee won't have to answer that question, as the former Pushing Daisies star is set to guest star on the upcoming Fox series.

According to E! Online, the part-time Broadway star will show up on a fall episode of Glee.

"She's kind of a drunk, a has-been. She's squatting in a McMansion in town, but she's still got it," Jane Lynch said of Chenoweth's character. "She's got the voice, she's got the moves and she really shows the kids how to put it on."

In other exciting, Gleeful news: look for appearances on the soon-to-be Fox hit by Josh Groban and Victor Garber.
