Tina Fey Previews Her New Mean Girls Musical

Tina Fey's new musical adaptation of Mean Girls is gearing up for its world premiere at the National Theatre in Washington, D.C., and Broadway newbie Fey is learning what it takes to put a show together.

On a recent edition of The Tonight Show Starring Jimmy Fallon, Fey revealed how much fun she's having in the rehearsal room, and what it's like to watch a group of young triple-threats strut their stuff. Watch the full clip below:

With a book by Fey (based on her screenplay), music by her longtime collaborator and husband Jeff Richmond, and lyrics by Legally Blonde scribe Nell Benjamin, the musical will run October 31-December 3, with a Broadway production to follow. Casey Nicholaw directs and choreographs, with Stuart Thompson and Lorne Michaels serving as producers.

Mean Girls is described as follows: "After years of living with her zoologist parents in Africa, Cady Heron moves to Illinois and must find where she fits in the social hierarchy. A sweet, naive newbie, Cady quickly attracts the attention of The Plastics, a trio of popular frenemies led by the vicious and calculating Regina George. When Cady devises a plan to end Regina’s reign, she learns that you can’t cross a Queen Bee without getting stung." Full casting and additional information will be revealed in the coming months.
