Watch Your Back, Sue Sylvestor! Molly Shannon Is Gunning For You!

This is going to be GOOD!

Yet another famous face is being added to the roster of celebs making guest-spots on Glee in the second half of the season. It has just been announced that Molly Shannon will be joining the cast as a nemesis to Jane Lynch’s Sue Sylvestor character!

Yes!

Molly will play Brenda Castle, a busty new astronomy teacher and badminton coach at McKinley High School who is described as being both an “alcoholic and a pill-popper.”

Oh hell yes!

Though, there a small, tiny bit of us that is disappointed she won’t be Mary Catherine Gallagher. It will still be amazing!

Don’t U agree?
