How big a Madonna fan are you? Enough to fork out upward of $40,000 for two tapes with steamy answering-machine messages she left a boy toy from 1992 to 1994? If so, keep your eye out for an upcoming rock' n' roll memorabilia auction that will feature the tapes, along with a "very personal and intimate video" from the Material Girl to the same gentleman, who at one point was also her bodyguard. Some blast-from-the-past personal faxes are up for grabs, too. The faxes sent to (you guessed it) the same ex feature such stimulating conversation as "my booty looked good [in a photo shoot] and you should see how good it looks in person." Apparently, a fling with a pop star is a good investment, too.
