Britney Spears On Set Of “Glee”

Britney’s ready for her closeup on Glee. Are you?

Britney Spears spent the day filming her guest spot on the FOX dramedy Glee.

”What’s up GLEEKS? Having so much fun on set!! Can’t wait for you guys to see the episode!” the platinum-selling pop tart Tweeted from the show’s Los Angeles set on Wednesday.

Brit even posted a picture from the set, which features her dressed in business casual attire along with some clear-framed spectacles.

Last week, Glee producers announced that Spears will be getting her own tribute episode on the show’s anxiously-awaited second season — complete with six Spears selections from her discography performed by the show’s cast. Among those songs is the 1998 charttopper “(Hit Me)..Baby One More Time” — Britney’s debut single and first international smash. That song will be performed by Lea Michele’s Rachel Berry.

Pop songstresses Madonna and Lady Gaga have also had their catalogues performed by the cast of Glee.
