MADONNA doesn’t think much of Paul McCartney‘s live performances. She tells Rolling Stone: “People have told me, ‘You could just go out there and play guitar and sing your songs like Paul McCartney,’ but I’d be too bored. Most of the joy of the shows is the magic of creating them — theater. I’m a perfectionist. I like hard work. I like to sweat.” She also revealed that The Post’s famous front page headlined, “Madonna: I’m Not Ashamed,” published after her nude photos appeared in Playboy, was proudly hanging in her home after being turned into art by her friends Keith Haring and Andy Warhol. She said, “They took all these Post covers and painted over them. They’re in my house in LA — a signpost, a watershed moment.” She added that her Sticky & Sweet tour was the only thing that kept her sane during her painful divorce from Guy Ritchie: “I think work saved me, and I’m grateful that I had work to do. I may have thrown myself off a building.”
