Madonna has already flashed crowds twice during her MDNA Tour, but this might be the most exposed she's been yet. According to InTouch Weekly, Madonna's tour rider would probably make David Lee Roth cry about pop-star excess gone rogue.

Per the tabloid, the Queen of Pop reportedly requires everything from 20 international phone lines to "light-pink roses that have stems trimmed to precisely six inches." Her 200-person entourage apparently includes a yoga instructor and 30 bodyguards.

"Madonna has probably the longest list of requirements of any of the world’s music stars," an unnamed source told The Daily Star (via The Daily Mail). "She expects things to be just right or it puts her off her stage show."

About that stage show: during a tour stop in Istanbul on June 7, Madonna flashed her right nipple to the adoring crowd. Then on June 12, while performing in Rome, Madonna pulled down her pants to reveal a black thong.

The 53-year-old singer will continue to trek through Europe this summer. The MDNA Tour makes its North American debut on Aug. 28 in Philadelphia. Workers at the Wells Fargo Center should start hiding the brown M&Ms right ... now.

CORRECTION: An earlier version of this post incorrectly joked that Wells Fargo Center workers should stock up on brown M&Ms. Using the old David Lee Roth trick as a guide -- the Van Halen front man would request that his dressing room be devoid of brown M&Ms as a way to make sure all the demands of his band's tour rider were met -- the brown M&Ms should be hidden.
