Katy Perry wants her fans to help choose the songs for her new 3D movie Katy Perry: Part Of Me.
The film will document her upcoming tour this summer (12) and she has asked her Twitter followers to give her track suggestions and advice on what clothes to wear for her stage performances.
Insurge Pictures president Amy Powell says, "It is a really fun and engaging movie that celebrates every aspect of Katy's life including her relationship with fans. What better way to kick start the filmmaking process than by inviting her millions of fans on Twitter into her world?"
