Katy Perry's 3D concert film, Part of Me, arrives in theaters on Thursday, July 5th.  And while the film definitely captures the candy-coated fun and excitement of Katy's California Dreams concert tour, it doesn't shy away from the emotional turmoil that Katy experienced during that tour.

In the film, the events leading up to Katy's split with husband Russell Brand are given a starring role, though obviously it's all told from Katy's point of view.  In the movie, Katy's shown going to great lengths to make her marriage work, flying off to see Russell between tour dates despite her exhaustion.

The topic of children was also evidently a sore spot for the couple; in one scene, after Brand sends Katy a text joking about what they should name their children, she says, "Babies can’t have babies, and I’m still a baby.”  When her marriage crumbles, Katy is seen having a breakdown, sobbing, but then putting on a brave face and going out and knocking the crowd dead.

"I'm OK with showing that real side and stripping that down," Katy told ABC's Elizabeth Vargas on Good Morning America.  "I just wanted to, kind of, show that, really, at the end of it all, I was just a normal girl, pretty plain Jane, who had an idea, planted a seed and watered it."

Speaking about including her divorce in the film, Katy told Vargas, "It's like a scar.  Sometimes you look on your legs or your arms and you see this scar, and sometimes they're bad, and it reminds you of the thing that you learned, or what not to do again, and these are valuable things. They're life lessons."

Katy's willingness to be open in the film -- right down to showing herself without makeup -- mirrors her approach to music, she told Vargas.  Asked why fans connect with her songs, Katy said, "Because I still try and tell the truth in them and that I'm not singing about how fabulous everything is."

Katy has said that this film closes the Teenage Dream chapter in her life.  So what's next for her?  She tells Vargas, "I don't know where I'll be in five years, but I will still be looking forward.  I do know I will make another great record.  I have a lot of material to cover!"
