'Mean Girls' Musical Is Progressing - Get the Latest Update!

Tina Fey‘s Mean Girls musical looks like it is progressing nicely!

“We definitely want to see some kind of shape by the end of the summer,” Jeff Richmond, composer and husband of Tina, said to Billboard about the stage adaptation. “With that in mind, we know that 60 or 70 percent of that will go away when we start bringing in real singers and actors. We’ll do a lot of rewriting…the most difficult part of the process is determining, ‘What are your best song ideas, and what do you leave alone as dialogue?’”

Mean Girls opened in 2004 with Lindsay Lohan, Amanda Seyfried, and Rachel McAdams in starring roles.
