Not only does it seem like the movie showcases her crazy life but also shows her appreciation for her fans.
And yesterday, Katy was all about showing some serious fan lovin'!
Several fans in London were lucky enough to check out a sneak preview screening of Part of Me. While at the preview they were quite surprised when Katy walked into the theater!
Not expecting the star at all, Katy sat in the audience and watched the film with her fans.
Seriously, how cool is that?!
"I actually feel like I know Katy Perry now, it's just like she could be your best friend and she'd be the most awesome friend ever!" one fan said after the screening.
Katy also kept busy in London by hanging with Florence and The Machine's guitarist Robert Ackroyd. She didn't look happy while they were out though...perhaps the divorce drama is getting to her? We hope not!
