Today, you can make Katy Perry part of your DVD collection. Her concert documentary,Katy Perry: Part of Me, is now available on DVD and Blu-ray.

There are three different versions from which to choose: a single-disc DVD, a two-disc Blu-ray/DVD/digital copy combo, and a three-disc Blu-ray 3D/Blu-ray/DVD/digital copy collection. All of them contain never-before-seen content.

E! Online has posted a deleted scene from the DVD in which Katy is introduced to a Barbie doll bearing her likeness.

Each copy of the film sold in the 48 contiguous United States also comes with a "Pink Ticket," which gives fans the opportunity to win prizes, including a meeting with Katy.

Katy Perry: Part of Me didn’t have an especially strong box office debut during the July 4 weekend, but it earned nearly 32 million dollars worldwide by the time it left theaters about two months later, according to BoxOfficeMojo.com.
