Let's hope Sue Sylvester won't somehow finagle another spot as a regionals judge on an upcoming episode of 'Glee,' because there won't be room for any more diva-tude at the judging table.

According to TV Line, both Kathy Griffin and Loretta Devine have signed on to play judges at New Directions' upcoming regionals contest -- and boy, do these characters seem way off from their real-life selves.

The liberal-leaning Griffin will play an ultra-conservative Tea Party candidate named Tammy Jean. Some sources say she's got shades of Sarah Palin about her, but according to TV Line that's not the case.

Devine, on the other hand, will play Sister Mary Constance, a nun with a dubious past -- as a stripper. No word on whether the former Broadway star will sing.

The two women aren't the highest-profile of guest stars 'Glee' has booked recently, but they're both big enough names to make us even more excited for the sure-to-be-epic episode.

Tell us: What do you think of the casting news?
