Britney celebrates her Glee episode
Britney Spears has celebrated her Glee episode with a pink TV-shaped cake.
The pop princess makes a cameo as a cheerleader in Fox's hit musical TV show, which pays homage to her with performances of her songs, including Toxic and Hit Me Baby One More Time in a special episode of the new series, which aired in the US this week.
Britney, 28, stayed in to watch the show and tweeted about how much she was enjoying it, writing: "Awww Heather Morris is sooo cute! Brittany S Pearce. Ha! She was so fun to work with and was really sweet in person."
As Heather, who plays cheerleader Brittany recreated her performance of I'm A Slave 4 U from the 2001 MTV VMA's with a live snake, Britney tweeted: "I know how hard it is to dance with that snake! Nice job..."
Lea Michele, who plays Rachel, also recreated the infamous Hit Me Baby One More Time school uniform and pigtail video and Britney had a cameo in the scene as a teacher.
The singer tweeted: "Watching Baby brings back so many memories! Feels like yesterday..."
Britney was full of praise for everyone in the show, especially singing fashionista Kurt (Chris Colfer) and Jane Lynch, who plays tough cheerleading coach Sue Sylvester.
She posted a picture of a pink TV-shaped cake which congratulated her on her episode and wrote: "I loved it! Thank you guys SO much for making this happen!"
Britney's episode was a US ratings hit, drawing an estimated 13.5 million viewers - making it the second most-watched episode of the show ever.
UK fans will have to wait until January before the new series is aired on E4.
