Katy Perry surprised Katy Cats who attended a special screening of ‘Katy Perry: Part of Me’ in London on Thursday night (June 7) by showing up and serving popcorn.

Before the film began, Perry popped on stage, saying, “Hi, is it alright that I’m here? We’re going to watch my movie.”

The singer then took a seat among fans, snapped some photos and generally showed that she is living the teenage dream. Perry also served popcorn at the concession stand.
