For fans who may have doubted whether the Britney Spears "Glee" episode is happening, the pop sensation has just provided photographic proof.
The star gave fans a glimpse of her inner-"Gleek" on Wednesday (August 18) by posting a TwitPic of herself next to her assistant Brett Miller, a Spears doppelgänger, both sporting similar specs and wavy blond locks.
After devoting episodes to the dance-floor-filling repertoires of Madonna and Lady Gaga, "Glee" is hard at work bringing Spears' string of hits to William McKinley High. So far, Spears, who makes a cameo in the upcoming episode, is enjoying the process.
"About to do my first shot of the day for Glee tweeties! Here we goooo!" Spears tweeted. The "Circus" singer later added, "What's up GLEEKS? Having so much fun on set!! Can't wait for you guys to see the episode!"
The "Glee" cast is also pumped to turn out Spears' smash-hit catalog. "I get to do Britney Spears!" Heather Morris exclaimed to MTV News earlier this month. "I like 'Toxic' the best or the 'Slave' video. It was always her best performance. She's rocking! I don't care what I do."
Jenna Ushkowitz confirmed that Lea Michele would take on Spears' star-making debut hit, " ... Baby One More Time." Aside from Spears' TwitPic — in which she's presumably in costume — and "Glee" creator Ryan Murphy's recent comments that Spears will "kind of" play herself, details about the episode have remained under wraps.
"Some old Britney, some new Britney, some Brittany of our Brittany from the glee club. So it should be funny," Ushkowitz hinted about the song selection. "We're really excited. I love Britney Spears."
