Madonna is firing back at an auction house who was looking to sell a letter Tupac Shakur wrote her while he was in jail.

According to TMZ, the "Like A Virgin" star filed an emergency court order today in order to block the sale of the letter, which she says was stolen from her. Other items, including a pair of her used panties, are also in the mix to be sold and Madonna was unaware that those things weren't in her possession. She thinks that a former friend had betrayed her and taken some of her belongings.

'Pac had written a very revealing letter to Madonna about why they couldn't continue to see each other, with race being a part of the issue.

Update: As per TMZ, the company that planned to sell the letter has released a follow-up statement:

"Madonna and her legal army have taken what we believe to be a completely baseless and meritless action to temporarily halt the sale of Ms. Lutz’s legal property. We believe that her intent is nothing more than to besmirch the good reputations of the auction house and Ms. Lutz. Madonna's allegations will be vigorously challenged and refuted in a court of law in due course."
