Britney won't appear in Glee special

According to People, Lynch, who plays Sue Sylvester in the show, said of the upcoming episode: "Britney's not in it. It's a tribute to her music."

"It's kind of [about] how Matt [Morrison]'s character Mr Schuster doesn't see any value in her and the kids really do."

"At the end [of the episode], he comes around and he likes [her music] so much, he shaves his head."
