Sue Sylvester is already a bit of a cartoon character -- and now she's really getting animated. Emmy winning 'Glee' star Jane Lynch is set to guest star on an upcoming episode of 'The Simpsons,' according to Entertainment Weekly.
Lynch will play Homer Simpson's new assistant at the Springfield Nuclear Power Plant, though she's secretly not assisting him succeed.
"This woman seems terrifically nice, but then it turns out she's just completely undermining him every step of the way and gets his job -- until he can discover her one weakness with the help of Ned Flanders," the show's executive producer, Al Jean, said.
This isn't Lynch's first appearance in a FOX cartoon -- last January, she made a guest appearance in 'The Cleveland Show,' playing, of all things, a teacher. Before that, she was in another Seth MacFarlane animation, 'American Dad.'
