Britney loved her Glee experience
Britney Spears is all smiles after her first day on the set of Glee.
The pop princess, the latest in a line of stars to appear in the musical-comedy TV show, couldn't wait to tweet about her experience.
She wrote: "About to do my first shot of the day for Glee tweeties! Here we goooo!"
After filming the episode, she took to Twitter to post a picture of herself on the show and tell fans: "What's up GLEEKS? Having so much fun on set!! Can't wait for you guys to see the episode!"
The show's co-creator Ryan Murphy has previously told how he admires how the Hit Me Baby One More Time and Toxic singer has turned herself around.
The episode is expected to showcase Britney's music but will not delve into her personal life, with Ryan saying on Ryan Seacrest's radio show: "We're handling Britney with kid gloves."
It's thought that the storyline will feature singers under anaesthesia at the dentist who hallucinate about Britney and being like her.
The Emmy Award-nominated show has become a massive hit for Fox and is shown on E4 and Channel 4 in the UK.
