In between dazzling shots of her onstage, in her music videos and getting dolled up in sparkling costumes, Katy Perry also addresses some real issues in her first full trailer for her 3-D concert film, "Part of Me," set for release in July. While she doesn't directly discuss her divorce from actor/comedian Russell Brand in the teaser, the split is referenced by a news headline as Perry is seen getting ready for one of her shows. And that's not the only personal subject the colorful pop star will open up about in the film.

Katy's Religious Background
Perry, now best known for her candy-coated, flirty persona, grew up in a strict, religious family. In the trailer, Perry talks about finding her voice while going to religious services with her family. She says, "The atmosphere I grew up in was 100 percent Christian. I started singing in church; I never really had another plan." Perry Gets Dropped From Her Label
While it might seem that Perry went from virtual unknown to chart-topping pop sensation overnight, Perry and her friends open up about the trying time she had between being dropped from her label and eventually finding success. "I was going through some depressing, dark times," she recalls, "but it's a journey, and I learned so much from that journey. I feel like a stronger, better person because of it." California Gurl Live Onstage
While the film is about her life behind the scenes, a major part of the movie is her eye-catching California Dreams Tour, which went all around the world in 2011 and early 2012. "You have to be really be grateful and know that it's a different set of people every single night," she says of hitting the stage. "My goal when I'm playing shows is just to make people smile." KP Lives out Her California Dreams
In the end, Perry's message is always about living your dream, no matter what strife might come your way. She has this advice for her Katy Cats: "If you have a dream, you gotta go on a journey to fulfill that dream." "Part of Me" opens July 5. 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. "Part of Me" is also the name of the lead single off Perry's just-released Teenage Dream: The Complete Confection album.
