MAY 19--As she prepares to embark next month on the U.S. leg of her 2011 world tour, Katy Perry will be carrying a 45-page concert rider that outlaws carnations, details very specific furniture requirements, and outlines a 23-point “principle driver policy” for chauffeurs in towns the 26-year-old singer visits.

According to Perry’s rider, excerpted here, the performer’s dressing room (which has to be draped in cream or soft pink) needs to be outfitted with two cream-colored egg chairs, one of which should have a footstool. It is unclear whether Perry requires original Arne Jacobsens or cheap knockoffs. A coffee table needs to be “perspex modern style.” A pair of floor lamps should be in “French ornate style.” And the singer’s refrigerator must come with a glass door.

As for the dressing room’s flower arrangement, Perry wants “White and purple hydrangeas, pink & white roses and peonies.” If those flowers are not available, Perry will settle for a “selection of seasonal white flowers to include white orchids.” However, promoters are advised, “ABSOLUTELY NO CARNATIONS.” That warning is, of course, underlined.

In a commendable effort to curb the environmental impact of plastic bottles, Perry’s rider notes that water dispensers must be provided in all dressing rooms and production offices, and that tour personnel will be supplied with “SIGG drinking bottles.”

When it comes to hotel provisions, Perry requires a “1 bedroom presidential suite” in a “5 star property.” And free Internet service and a complimentary breakfast must be provided to the performer and her touring party.

Chauffeurs, the rider notes, are not allowed to “start a conversation w/ the client.” Wheelmen are similarly barred from conversing with Perry’s guests or fans. They also are directed not to stare at the backseat through the rear view mirror. Drivers should also not “ask for autographs or pictures, and especially not while driving!” Finally, Perry’s ride should be outfitted with four water bottles (presumably in the event she forgets her Sigg).

The rider also alerts promoters that they may be required to hold back tickets for concerts so that Perry & Co. can provide the ducats to “resellers” for “distribution to the public” on the “secondary market.” In other words, Perry reserves the right to pocket some of the proceeds from the sale of tickets--not made available at face price to her fans--scalped at inflated prices by these brokers.

The quantity and location of tickets earmarked for these secondary markets will be determined by Perry’s “Personal Manager,” according to the rider, which was provided to TSG by our pal Jester. (6 pages)
