"[Pink] could not be a more ideal fit for this role," first-time director Stuart Blumberg told Entertainment Weekly. "She carries with her just the right combination of heart and edginess for the part of Dede, and we're incredibly excited to share her acting talent with audiences."

As "Dede," the star (real name: Alecia Moore) plays a "free spirited" sex addict who bonds with a young man named Neil (Josh Gad).

The "Raise Your Glass" singer, who welcomed first daughter Willow Sage with hubby Carey Hart in June, has indeed acted before, with appearances in Charlie's Angels: Full Throttle, Rollerball, Catacombs and Happy Feet Two.
