Katy Perry Part of Me Pictures

1 / 11

Katy Perry's 3D concert movie, Katy Perry: Part of Me, opens this week, and we've got an exclusive peek at what you can expect from the film. Not only do we see Katy looking gorgeous all dolled up in her various costumes, but we also get a behind-the-scenes look at her rehearsals, what happens in her dressing room, and more! Take a look at the images before the film hits theaters on July 5.
