Get ready to see Britney Spears on Glee.

"Britney, I think, 100 percent is going to be on the [upcoming] episode" that's dedicated to her pop hits, Glee co-creator and executive producer Ryan Murphy told Ryan Seacrest on his radio show Tuesday morning.

Is Glee reaching too far with a Britney-themed episode?

The Season 2 episode will feature the Glee kids performing numbers from the singer's career during a fantasy sequence at the dentist's office. Spears' exact role hasn't been ironed out, but she could play the dental assistant to John Stamos' character, Murphy said.

Murphy insists that the episode will not poke fun at the singer, who's had her share of ups and downs. "The Britney episode is so reverential about her and so kind, and it's about her music," he said. "She's been through a lot and I want to do something that says ... thank you for what you've done, and we're encouraging you to be doing as fantastic as you are."
