Watch: Katy Perry (Part Of Me) 3D Movie Trailer

Katy Perry has released the trailer for her 3D movie titled "Katy Perry: Part of Me".

The documentary style cinema offering is modeled after Justin Bieber's "Never Say Never," as the material is comprised of video footage collected during the "Firework" tour, along with photos and family clips from before her rise to stardom.

Revealing that her singing days first started in the church choir, Katy tells in the trailer, "The atmosphere I grew up in was 100 percent church. I started singing and I never really had another plan."

With the full "Part Of Me" 3D film set to hit theaters on Fourth of July weekend, Miss Perry adds, “If you’ve got a dream, you have to go on a journey to fulfill that dream."
