The rocker will executive produce the film under her company Blackheart Films, as well as star in a supporting role.
The dark romantic film will star Jett as a Venice Beach folk singer who befriends a couple during an AA meeting.
Estella Warren and John Philbin will play the romantic leads, with the cast also including Daryl Hannah, Margaret Cho, Meredith Baxter, Tom Arnold and Shannen Doherty.
Jett last executive produced The Runaways, the film about her all-female punk band in the late '70s. Kristen Stewart played her in the film, which Jett described as "Surreal".
The rocker also recently released a new album called Unvarnished. She's revealed that she will never retire from music.
