made her eighth visit to “Letterman” last night, arriving through the door of The Ed Sullivan Theater carried by a slew of handsome hockey players. “It’s the one sport I haven’t explored,” Madonna later quipped — a reference to her well-documented dating history with a variety of sports stars. Letterman asked about her recent divorce and she joked that her marriage lasted through the “Bush years,” when it was a “good time to be out of America” and that she’d rather “get run over by a train” than ever marry again. They ended the interview with Madonna’s first slice of NY pizza, which she probably spit into her napkin when the cameras stopped rolling. After all, she doesn’t like cheese on her pie. Clip above.
