Since first announcing she'd be starring in her own 3-D concert movie, "Katy Perry: Part of Me," Katy Perry has kept fans in the loop about the film. In keeping with that routine, she's just revealed the release date for the summer flick.

"My concert documentary is coming out Fourth of July weekend. Go and see it and be a firework!" she told E! News at the Kids' Choice Awards. The film was directed by Magical Elves Dan Cutforth and Jane Lipsitz, who also served as producers on Justin Bieber's highly successful "Never Say Never" concert movie.

"The atmosphere I grew up in was 100 percent church. I started singing and I never really had another plan," she said in a TV spot that began airing over the weekend, which is also full of vintage, behind-the-scenes footage of the singer. After kicking it old-school, a montage of her music videos leads up to colorful concert footage of the singer from her California Dreams Tour.

"If you have a dream, you have to go on a journey to fulfill that dream," she says in the clip. The tease closes out with Perry dressed up as her "T.G.I.F." alter ego, Kathy Beth Terry.

"This film, you're going to see it from my best friend/ buddy perspective, you're going to see exactly what I mean and feel and think about everything," Perry recently told MTV News. "Listen, I've [worked on] most of this film for a very long time and the word 'cheap' was not in the vocabulary," she said. "But, hello, it's 3-D. You're going to get hit with a lot of sh--." To add to the excitement for the movie, Robert Pattinson and Kristen Stewart were recently spotted shooting something that will appear in the film.

"That tour was so life-changing to me. I learned so much, I went through so much along the way," Perry said. "I'm not necessarily trying to prove anything to anyone, but not only will people really hands-down know me after they see this film, but you'll see me as the Dorothy wearing the red ruby slipper, and at the end of it all I'm the [Wizard of] Oz as well."
