After this week's amazing Glee episode that featured all Madonna songs, celebs are lining up to be featured in the hit series -- including Britney Spears!

"Do you guys want to see a Britney Spears episode of GLEE?" her manager tweeted last week.

He even started a new hashtag, #BritneySpearsGLEE, which has been trending on Twitter.

But Brit's not the only celeb who wants a piece of Glee, Jennifer Lopez says she's dying to appear on the show. “I sat down with [show creator] Ryan Murphy and we talked me doing something on Glee," she told Ellen Degeneres yesterday. But Lopez won't be getting the Madonna treatment. Murphy previously said he had something else in store for Lopez: he wants her to play the lunch lady. "“I was like, ‘Yeah, yeah whatever. I’m a huge fan,’" Lopez said.

Glee will be debuting a Lady GaGa episode later this season, and Murphy told Entertainment Weekly earlier this week that he's in talks with Madonna for another episode featuring her extensive catalogue.
