Celebrity couple Katy Perry and John Mayer have some unusual demands when they check into hotels.

Thirty-six-year-old singer-songwriter Mayer requests that an aged bottle of Lagavulin 16 scotch, water, soda and a fruit platter be placed in his room before he arrives.

His 29-year-old popstar girlfriend Perry also has demands of her own, requesting that a huge bowl of ranch dressing, along with nearly two dozen other snacks, six types of drinks, a full-length mirror, a coffee maker and a director's chair are in place before she arrives.

A source close to the couple told Life & Style Magazine: "John and Katy get VIP treatment wherever they go.” 

The source added: "It's usually all the same items for TV shows, backstage at concerts and hotels."
