Since by now half of the Cheerios are members of New Directions, Glee is enrolling a new crop of Mean Girls! Who’s who?

* Sugar is… well, she’s basically RHNJ’s Danielle Staub, only in high school. Affluent, self-confident and a godawful singer.

* Sheila, a modern-day Joan Jett, actually has her own pack of Blackhearts and the tats to go with ’em.

But that’s not all. As production on Season 3 gets underway next week, I’m hearing that the show is also on the lookout for a new linebacker, a gigantosaur by the name of Bubba. (What did you expect, a Kevin?) As previously revealed at Comic-Con, Bubba will introduced as Mercedes’ new beau, whom she started dating over the summer.

Also, sixtysomething actresses will be passing through to audition for the role of Nancy Bletheim, a geometry teacher who thinks the arts are for… well, anywhere but in school.

Any ideas about who should play the parts? Hit the comments!
