Glee just can't keep the celebrity guest stars away! The show will use the plot device of Sue's burgeoning celebrity status to attract celebrity judges to Regionals on the June 8 Glee season finale. Sue will be one of the judges, and joining her will be Olivia Newton-John and previous guest Josh Groban! Let's see... the judges are Olivia, Josh, and Sue?! Considering she found a way onto this judging panel without knowing a single thing about music, it looks like Sue is more persuasive than we realized!

According to creator Ryan Murphy, Josh and Olivia will play versions of themselves who "only like choirs that sing their songs," since both stars wanted "to play against type." Looks like Sue won't be the only self-absorbed member of the panel.

And the finale, which shoots this week, is already getting buzz. Matthew Morrison calls it "the best episode I have ever read of the show" and says he was "bawling" while reading it. Okay, so he may not be the most impartial critic in the world, but if it made him cry, we think it may be a safe bet to stock up on some tissues!
