Britney Spears is to become the latest, and probably the biggest, celebrity to cameo on hit TV musical comedy 'Glee.'

Creator Ryan Murphy told Ryan Seacrest (via Billboard) that the once teen sensation will appear in an episode entirely dedicated to her music.
"Britney, I think 100 percent, is going to be on the episode. She is going to join us for a couple of scenes."

Murphy also said that, though the show is often quite satirical, Britney's episode would be "reverential...and so kind...We are handling Britney with kid gloves".

Madonna and Lady Gaga have also had episodes of 'Glee' devoted to them, and a Coldplay dedicated show is also in the making after the band originally refused to let producers feature their songs.
