Glee's Special X-Mas Treat: SuBo!

Susan Boyle has finally been nailed down for her appearance on Glee!
The Scottish sensation will be gracing the kids of McKinley High this Christmas, filming a special cameo for their holiday episode. A source calls her role “great fun.”
Wonder if she is still going to be the lunch lady? A festively singing lunch lady! We think that’s fun!
Thoughts?
