Madonna lost her appeal to block the breakup letter Tupac Shakur sent her among other personal items. Madonna’s former friend and art consultant, Darlene Lutz, consigned several items, including the letter to her online auction house, GottaHaveRockandRoll.com. Last year a judge dismissed Madonna’s case against Lutz after paperwork surfaced that had Madonna signing off on a release which prohibited Madonna from suing over the sale of the letter. In the love letter, Tupac told Madonna that they had to break up because she’s white. The letter, along with other personal Madonna items will be auctioned off next month.
