Katy Perry

When Katy Perry is on tour she wants her dressing room outfitted in a very specific way. It's to be draped in cream or soft pink linens, and adorned with fresh flowers, but "ABSOLUTELY NO CARNATIONS." And if you're one of Perry's drivers, don't assume she wants to be your friend. Her rider notes that drivers are not allowed to "start a conversation with the client," and are not to make eye-contact with her via the rear-view mirror.
