Katy Perry is gearing up for the release of her 3D biopic 'Part of Me,' set to hit theaters on Thursday, July 5. She's been promoting the movie over the past few months with sneak peeks of the film, interviews and a series of colorful posters. All four of the posters that have been circulating are eye-catching and awesome, but which one is the best 'Part of Me' poster?

In one poster, Perry is pictured as a younger version of herself singing into the mirror. She's singing into the mirror in what's supposed to be her bedroom, envisioning herself as the pop superstar she is today. In the second vibrant poster (you can see them all below), a purple-haired Perry is seen in a sea of popcorn wearing a pair of heart-shaped sunglasses as she spills her movie munchies.

Finally, Perry held a voting contest on her official Twitter account to decide which promotional poster to use as an added visual. We thought both patriotic 'Part of Me' posters were so cool, we've decided to include both of them. Both are inspired by the Fourth of July and Perry's Grammy-nominated tune 'Firework,' with the songstress sporting an American flag tee, holding up her index finger in one while smiling in another.
