A new musical based on the late Adrienne Shelly’s 2007 movie “Waitress” is coming to Broadway this spring, featuring a score by five-time Grammy-nominee Bareilles (“Brave”).

The show tells the story of Jenna (played by Kerri Russell in the film), a small town pie maker who enters a baking contest in hopes for a chance to escape her mundane life and her loveless marriage.

No official Broadway theater, dates or casting have been announced, but the musical is currently being workshopped at the American Repertory Theater at Harvard University in Cambridge, Massachusetts, with Tony winner Jessie Mueller ("Beautiful") starring as Jenna.

Direction will come from Tony-winner Diane Paulus (“Finding Neverland,” “Pippin”), with a new book by Jessie Nelson.

Bareilles most recently served as a judge on NBC’s “The Sing-Off.” This will be the first Broadway musical she has composed.
