Loretta Devine, better known to Grey's Anatomy fans as Chief Webber's no-nonsense wife, Adele, snagged a pretty big guest spot aside from the 5-episode arc she just landed on Grey's Anatomy. She's set to guest star alongside Kathy Griffin on an episode of Glee.

The two will both play judges in the highly anticipated trip to regionals episode, where McKinley High's New Directions will compete for a spot at nationals. Kathy Griffin's character, Tammy, is a spoof on — who else? — Sarah Palin, while Devine plays an ex-stripping nun named Sister Mary Constance. Who better to judge a Glee competition?

No word yet on when the episode airs, but it will probably be towards the end of the season in some big lead up to the finale. Bring on Loretta's comedic comeback!
