Katy Perry’s documentary movie Part of Me is just under a month away from hitting theaters.

She released a second poster for her movie, which follows her life on her California Dream tour.

Katy also hit up London to promote her movie, but instead of doing a regular promotional tour, she decided to do something a little bit different. So she went to a local movie theater and passed out popcorn to fans!

Afterwards, she sat down with her fans in the theater and donned her very own pair of 3D glasses to watch a movie.

Part of Me comes out on July 5th.
