We recently learned the reasons for Madonna and Tupac Shakur’s breakup, via a letter the late artist wrote the erstwhile Material Girl from prison. In it, Shakur described the disparate effects of their relationship—while the revelation would just make her seem more “open and exciting,” it might be seen as a betrayal to his fans. Although much of it was redacted before being set for auction at Gotta Have It Collectibles, it’s still clear that the letter was a poignant read, one which Madonna is now claiming she inadvertently let out of her grasp.

As Reuters reports, the pop superstar has filed a request to prevent that letter and several other personal items from going up for auction. Madonna says Darlene Lutz, the woman who‘s auctioning the items through Gotta Have It, “betrayed [her] trust in an outrageous effort to obtain my possessions without [her] knowledge or consent.” Somehow, Lutz, “a former friend and art consultant,” got her hands on the breakup letter as well as one in which Madonna despaired of not being as successful in music or film as Whitney Houston and Sharon Stone, respectively, calling them “horribly mediocre.”

That letter’s probably a greater embarrassment for Madonna than the “pair of her panties, an old checkbook, a hairbrush and personal photos“ that are also being auctioned, but she’s going after the whole lot. But a joint statement from Lutz and the auction house called the filing a “completely baseless and meritless action,” and indicated they’re ready to fight Madonna in court over these personal items. The sale went live today, but as of now, it doesn’t look like the letters, panties, and hairbrush are part of it.
