“Britney, I think 100 percent, is going to be on the episode. She is going to join us for a couple of scenes.”
When asked who’s idea it was, Murphy responded, “Well, it’s her idea. She sort of wants to do a ‘Where’s Waldo?’-type thing with ‘Where’s Britney?'”
Ryan then goes on to say that Britney will “kind of” be playing herself and describes the scene as a fantasy sequence involving Glee characters in a dentist chair hallucinating about being Britney.
Ryan, who says he’s been a fan of Spears for years also cites that the cast (except Matthew Morrison, who told US Weekly back in May, “I hope our show doesn’t go that route.”) is the reason for the pop star’s upcoming appearance. “So many of the kids on the show say, ‘We grew up with Britney. We want to do Britney. So I said, ‘OK,'” adding, “but I’m filled with admiration for her.”
