Lea Michele was psyched about starring on Glee from the moment she read the script.

But now that the show has lined up a slew of talented guest stars, the actress can't stop gushing about next season.

“We already had Josh Groban, Kristin Chenoweth, Victor Garber and Debra Monk come in,” Michele said to TV Guide Magazine, adding that Wicked alum Chenoweth will appear as a high school dropout “who’s a fantastic singer who comes in to join the Glee Club.”

While the young star - who plays Rachel Berry on the series - won't reveal details on Garber and Monk’s character, she says fans are in for an exciting fall.

“We’ve had a bunch of guest stars and they made the show so fantastic. In my opinion, the show is like a ten and then you have these people come in and they make it like 100!”
