It's been 14 years since we were graced with the glory that is Mean Girls, and on Sunday (April 8), the iconic movie got the theater treatment with the opening of its Broadway musical.

Tina Fey was, of course, in attendance on the appropriately pink carpet, and Entertainment Tonight! caught up with the film's writer and hilarious Ms. Norbury to chat about her favorite line from the 2004 movie.

"I don't know if its broadcast-able, but it's my favorite line—I usually say, It's not my fault that I have a heavy flow and a wide set vagina,'" Fey, who also wrote the book for the musical, revealed.

"It's really exciting to be here. I feel a little bit like its our wedding again because we're like, 'OK, who's got Grandma? Who's driving,'" she jokingly added. "I'm really excited for this young cast, for people to see them. They're so good."

The topic of 30 Rock was also discussed, and the 47-year-old comedienne revealed the possibility of future episodes.

"Oh my gosh, we'll see... We would know by May [at the NBC upfronts] if there was a great idea for a reboot... I don't know what's gonna happen," she admitted.
