We learned a lot about Katy Perry on her 96-hour Witness World Wide live stream event.
But nothing was so honest as being woken up by James Corden and playing a game where they had to answer hard questions or eat disgusting food.
Fans learned who Katy Perry thinks is better in bed: Diplo, Orlando or John; who James Corden turned down for Carpool Karaoke; and Katy's reaction to "what's your least favorite city to perform in."
