Katy Perry played ‘Who Knows Katy?’ with a super fan on Monday’s Jimmy Kimmel Live.
The “Dark Horse” singer went against Emily, a huge Katy Cat, in a battle of all things Katy. If the singer won, she would get Emily’s most prized possession, her Katy Perry scrapbook, and if Emily beat out her idol, she would go home with Katy’s pillow, autographed by the singer.
Who won? Watch video above to find out.
