Over the next several months, Twitter and Paramount will offer multiple opportunities for Katy's Twitter fans to play a role in helping to shape the final film.

From helping to choose which songs Katy will sing, to weighing in on her always exciting wardrobe options, this first-of-its kind interactive experience will set a new precedent for engaging movie going audiences on Twitter.

Fans can visit www.Twitter.com/KatyPerry to get involved. They can also follow Katy on Twitter to see exclusive behind-the-scenes content of the movie, which will provide fans a first-ever big-screen look at the international superstar's life both on and off-stage.

"Katy Perry: Part Of Me is a really fun and engaging movie that celebrates every aspect of Katy's life including her relationship with fans," said Amy Powell, President of Insurge Pictures. "What better way to kick start the filmmaking process than by inviting her millions of fans on Twitter into her world."

"Millions of Katy's most passionate fans use Twitter every day to hear directly from her and get a unique glimpse into the life of one of music's biggest stars," said Dick Costolo, Twitter CEO. "With this new approach to filmmaking, Paramount is taking the connections forged on Twitter one step further by empowering people to take part in the movie."
