It’s been two months since we first heard that the colorful pop singer Katy Perry would be hitting the screen in 3D. Well, guess what, there’s already a trailer. Katy Perry’s Part Of Me is due out Fourth of July weekend. The trailer recently hit the web, and from the looks of it, the concert movie is exactly what we expected it would be. Check it out.

Part of Me will focus on Perry’s ups and downs; her Christian upbringing; her rise to stardom; her mega success; her divorce from Russell Brand; and how she’s still standing strong. Doesn’t sound all that different from Justin Bieber‘s Never Say Never, does it? Minus the divorce part of course.

Perry told MTV News that in the film would tell a lot of her personal life.

“You’re going to see exactly what I mean and feel and think about everything.”

She promises that she’s not out to prove anything though.

Although the trailer is out, there are ways you  can be in it, if that’s what you want. Go to www.katyperrypartofme.com/submit and be sure to 1) Submit a video of you singing along to “Firework”, 2) Submit a video of how Perry inspires you, or 3) Upload a photo of you at one of Perry’s concerts.

Alright, here’s the trailer. Part of Me is out July 5, 2012.
