After learning this, I can't understand how Katy Perry stays so thin. According to Life and Style Magazine, Katy insists on having an ENTIRE bowl of ranch dressing as well as 20 other snack type foods. She also insists on having a full length mirror in her dressing room at all times. I guess its to see if any part of her body is growing from said snacks! LOL. Katy also likes to sit in a directors chair. They have one put in her dressing room at every performance. I can't see why she would. They're not very comfortable. She should ask for a Italian leather sofa put in her dressing. I bet she could get it done.

The magazines also reports that John Mayer is much less demanding. The 36 year old is happy with a simple bottle of aged scotch, water, soda, and a fruit platter.
