Andrew Morton, 47, is now poised to do to Madonna what he's already done to Princess Diana and Monica Lewinsky -- get her between the covers. The British biographer, whose 1992 "Diana: Her True Story," written with the cooperation of the princess, made him a millionaire, plans to publish his unauthorized look at the Material Mom this November. St. Martin's Press in New York has picked up the North American rights and is talking about a 500,000-copy first printing. "Andrew loves complicated women and has a genius for getting into their psyche and telling the world what makes them tick," St. Martin's publisher, Sally Richardson, said in a statement. Morton's other best-seller, "Monica's Story," about former White House intern Monica Lewinsky, was published in 1999.
