Aside from that one odd photo of Katy Perry that Russell Brand posted of her sans make-up, we've not had much of an opportunity to see the sexy pop star in her natural state. Well, that's going to change when her film, "Katy Perry: Part of Me 3D," is released on July 5th.

"When you see the film, it's a bit scary because there's a lot of shots of me bloated with zits and normal," Perry told Ellen DeGeneres two weeks ago. "I think it's important to start breaking down the idea that to achieve your dream you always have to be perfect or flawless or live in some kind of fantasy world. So that's why I decided to put everything into the film, in the most tasteful way. But mostly it's about how I go there and the ride along the way which can be bumpy but mostly it was extremely fun."

And a new trailer shows just what she means by that. Check it out.
