When it comes Katy Perry’s new concert film, ‘Katy Perry: Part of Me,’ the pop star will ask fans to help her make a few tough decisions. Over the next several months, Twitter and Paramount will jointly offer Perry’s 16 million Twitter followers a chance to play a role in shaping the final film — from helping choose which of the ‘Teenage Dream’ singer’s performances will be featured in the film to weighing in on her colorful wardrobe options. Perry will be tweeting exclusive behind-the-scenes content of the movie leading up to its summer premiere, which will provide fans a glimpse into the international superstar’s life both on and off-stage — as well as “the most intense year of her life.” The singer, who recently released her video for her new single ‘Part of Me,’ told MTV News that fans can expect to see things from a “best friend/buddy perspective.” Perry recently released ‘Teenage Dream: The Complete Confection,’ which includes her new single ‘Part of Me.’ The song debuted at the Billboard Hot 100’s top spot in February, after she premiered the track at the Grammys.
