'Glee': Ryan Murphy says Britney Spears is '100 percent' appearing in her episode

Paparazzi shots confirm that the Briney Spears episode of "Glee" is already in production, and creator Ryan Murphy is offering up an uncharacteristically generous helping of details on the Season 2 homage.

Murphy tells Ryan Seacrest this morning, "I think Britney, 100 percent, is going to be on the episode."

But how is Ms. Spears getting to Lima, Ohio? Well, she's not. New Directions' pleas for Britney tunes fall on deaf ears with Mr. Schuester (Matthew Morrison), so when they pay respective visits to the dentist (John Stamos), anesthesia-induced fantasies bring out the musical numbers and the all-but-official Britney cameo.

And if you're worried these rumors of a shaven Mr. Schu might dissuade Britney from dropping by, relax. Murphy says there won't be any references to Spears' personal life or darker days. "[This episode] is so reverential, so kind and about her music," he says. "We're handling Britney with kids gloves."
