It's always interesting to hear about popular star's backstage demands. Some requests can really be unusual, and what we would automatically consider to be "not normal."

So recently, when Life & Style Magazine revealed that Katy Perry needs an entire bowl of ranch dressing, and over 20 other random snacks in her dressing room at all times, I couldn't help but wonder what exactly she's thinking.

Being a popular star in the music industry and all, you would think she'd want to keep her figure under control. Oh wait ... Maybe that's where the mandatory full-length mirror comes in.

I'd love to get the opportunity to ask her about her backstage needs one day, and to see how she keeps her figure looking how it does in this behind-the-scenes video below.
