Who Knows More About Katy Perry, Katy Perry or a Superfan? - VIDEO

Katy Perry faced off against a Katy Perry stan (read: super fan) last night on Jimmy Kimmel Live! to see who knew more about Katy Perry, the woman herself or a rabid fan.

The game show was called "Who Knows Katy" and each contestant was playing for something owned by the other.

For example, if Katy won she would get super fan Emily's Katy Perry scrapbook and if Emily won she would be gifted with an autographed Katy Perry pillow.

So who knows Katy better?

Spoilers: not Katy.

But really the true winner is us, because we now know that Katy Perry was suspended from school in sixth grade for humping a tree.

True story.
