Madonna speaks frankly in an interview in the new Rolling Stone on just about everything except what happened to her on Dec. 28. According to the tabloids, that was the night her estranged husband, Sean Penn, left her tied up in a chair for nine hours. Madonna filed charges against him and later dropped them, but she says the tabloid reports are "extremely inaccurate, as they usually are. They made it all up." She's keeping the real story to herself. "People want to hear the dirt," she says, "but this is not really anything I want to talk about here. It's totally unfair to Sean, too." Madonna's new album, which was premiered Thursday night on a Pepsi commercial, includes a song titled "Till Death Do Us Part" that is about the violent breakup of a relationship and sounds quite autobiographical.
