She’s a “material girl” — and those are her materials.

Madonna sought an emergency court order Tuesday barring an auction house from putting an array of her memorabilia up for sale, including her private letters, “personally worn panties” and a handwritten letter to her from her former boyfriend Tupac Shakur while he was in prison.

In an affidavit, the singer says that on July 8 she became aware of the planned auction by Gotta Have Rock and Roll of many of her belongings, which she thought were still in her possession.

“I became aware through media reports that there was a planned auction of extremely personal, private correspondence I received from a former boyfriend, the late recording artist and actor Tupac Shakur,” Madonna said.

“I was shocked to learn of the planned auctioning of the Shakur Letter, as I had no idea that the Shakur Letter was no longer in my possession. I have never sold, gifted, transferred or otherwise disposed of the Shakur Letter.”

The papers seek an order from a judge halting the online auction, scheduled for Wednesday, of more than 100 items.

Madonna points the finger at Darlene Lutz, an art consultant and “former friend” who she had welcomed into her homes.

“It seems obvious that Defendant Lutz betrayed my trust in an outrageous effort to obtain my possessions without my knowledge or consent and now attempts to profit by auctioning off my personal belongings and private communications to the general public in complete disregard of my rights, especially my right to privacy,” the “Material Girl” singer said.

The suit says the items include private letters and other correspondence between Madonna, her family and celebrities and former boyfriends, private photographs, unreleased recordings, a personal checkbook, previously worn underwear and a hairbrush with the singer’s hair.
