Comedian joins the show, but not as a Sarah Palin look-alike

Careful Coach Sylvester, Kathy Griffin is headed your way.

The comedian and My Life on The D-List star has landed a guest spot on the hit Fox series as a judge at the upcoming Regionals competition, TV Line reports. While it's been rumored that the character was inspired by former Alaskan governor (and frequent Griffin target) Sarah Palin, a source tells the site that Griffin will play Tammy Jean, a homeschooling Tea Party candidate who will most likely clash with some of the other characters’ (i.e. Sue's) core values.

Griffin will be joined at the judges' table by Grey’s Anatomy star Loretta Devine, who will play Sister Mary Constance, a stripper turned nun who may be able to show Finn (Cory Monteith) a thing or two about choreography. —EMILY EXTON
