'Glee' Creator On Britney Spears Cameo: 'It Was Like The President Had Come'

'I couldn't get into my own sets at one point, which I thought was hilarious,' Ryan Murphy says.

Britney Spears may be a pop princess, but "Glee" creator Ryan Murphy felt as if the president had stopped by the set during Spears' recent visit to William McKinley High. Murphy dished about what went down when the singer filmed her cameo for the "Britney/Brittany" episode.

"It was literally like the President had come," Murphy told E! Online. "We all had to wear wristbands. I couldn't get into my own sets at one point, which I thought was hilarious."

Murphy thought Spears was moved by the cast's admiration for her. "I think she was really impressed about how so many kids of the show do what they do because they grew up wanting to be Britney Spears," he said. "She was really sweet with them. We had a number with a bunch of 8-year-old dancers in the show and she spent a lot of time talking to them, and they did the number for her ... She was so sweet, she's great with kids, she was so awesome."

But security remained tight, Murphy said, because "everybody was sort of trying to get into the set and find out what the hell she's doing in the episode." What Spears will be doing on the show is still unknown, but a picture the singer tweeted from the set suggests that she may be playing some sort of receptionist.

Aside from hanging with the pop princess on set, the "Glee" creator also got to hear some of Spears' new material. "I got to hear some of the music she's putting out later this fall or early next year," Murphy said. "It's really a great return to form for her; the songs are amazing so I feel she's riding the crest."

And while there has been talk of Madonna tunes blaring the speaker intercoms once again, Murphy has also

Last week, the singer tweeted photos of herself on set alongside Murphy and castmember Heather Morris. Posing in front of a set that looked similar to the singer's "Me Against the Music" video backdrop, Spears channeled the Madonna look that was donned in their 2003 collaboration.
