Playbill.com broke the news of the musical in June 2013 when Tony Award-winning producers Barry and Fran Weissler revealed that they were collaborating with their Tony-winning Pippin director Diane Paulus on the new musical to be scored by Grammy Award nominee Bareilles.

Waitress will begin previews in Cambridge, MA, Aug. 1, 2015. Paulus is the artistic director of A.R.T.

The New York Times previously reported that Jessie Mueller, who earned the 2014 Tony Award for her performance in Beautiful: The Carole King Musical, will star in the production. Representatives for A.R.T. could not confirm Mueller's participation.

Workshops of the new musical have been taking place the past several weeks in New York City.

"Corrina Corrina" screenwriter, director and producer Jessie Nelson has penned the book for Waitress.

Waitress tells the story of a woman, trapped in a job she hates, whose life changes when she discovers she is pregnant. Kerri Russell originated the role on screen.

A Broadway run is likely for the high-profile project. The Weissler's Tony-winning revival of Pippin premiered at A.R.T. prior to its acclaimed Broadway arrival. They are also attached to the A.R.T. production of The Heart of Robin Hood, which arrives on Broadway this spring at the Marquis Theatre.

According to A.R.T., "Based upon the motion picture written by Adrienne Shelly, the new musical follows the story of Jenna, an inventive waitress trapped in a small-town diner and a loveless marriage. Pregnant and lonely, Jenna finds relief in making creatively-titled pies — and in a budding romance with an unlikely newcomer."

Below, Bareilles performs "She Used to Be Mine" in concert and describes how the song fits into Waitress.
