Madonna Files Order to Stop Auction of Tupac Breakup Letter.

Madonna filed a request for a temporary restraining against the auction house Gotta Have It Collectibles to stop the sale of several personal items, including a breakup letter from Tupac Shakur, Reuters reports.

The pop star is seeking to remove 20 items from the sale. These include a pair of underwear, an old checkbook, a hairbrush, personal photos,the Tupac letter and another previously reported missive.

That note – addressed to a "J" believed to be actor John Enos, whom the pop star briefly dated – was expected to fetch at least $5,000 because in it Madonna called Whitney Houston and Sharon Stone "horribly mediocre."
