Looks like Britney Spears is the new Queen Bee at McKinley High!

On Thursday, the singer Tweeted a snapshot of herself on the Glee set with Heather Morris (who plays ditzy cheerleader Brittany on the show).

"All my GLEEKERS in the crowd, Grab a partner take it down," Spears wrote in the caption (referencing "Me Against The Music," her hit collaboration with Madonna).

Shortly after, Spears posted a follow-up photo of herself with Morris, 23, and show creator Ryan Murphy.

"Had so much fun on set today. My new BFFs," the singer, 28, added.

Earlier in the day, Spears teased that she was "shooting a really cool scene today that I know you guys will love."
