Tina Fey is almost as excited as we are about her new Broadway-bound musical adaptation of Mean Girls, which makes its world premiere this fall in Washington, D.C.

Appearing last week on The Tonight Show Starring Jimmy Fallon, Fey told her former SNL castmate that the show, which begins previews October 31 and runs through December 31 at the National Theatre, has been in rehearsals for about a month.

“It’s so fun,” Fey said. “I’ve been in stuff that’s like movie musicals or whatever a little bit, and the secret with movie musicals is you can secretly suck and be a star, but to do things onstage, these kids are so talented."

“They're, like, a bunch of baby Timberlakes,” she added, referring, of course, to multi-hyphenate performer Justin Timberlake. “Everyone can do everything. They just sing so loud and dance so hard."

Because of the D.C. theater's close proximity to the White House, Fey also joked, "if you work there and you get fired, come see the show."

Fey wrote the book for the musical, which is based on her classic 2004 comedy. It features music by her husband, Jeff Richmond, and lyrics by Tony nominee Nell Benjamin. Tony winner Casey Nicholaw directs and choreographs.

Although no official announcement has been made about a Broadway start date, a recent Equity casting notice points to March 2018.
