Whereas other books about Madonna have been based on previously published material, this biography is the result of fifteen years of exclusive interviews with people who are speaking publicly for the first time, including close friends, business associates and even family members. Acclaimed biographer J. Randy Taraborrelli has also interviewed the star herself on numerous occasions and he draws on these first-hand experiences to bring Madonna to life as not merely a tabloid delight, but as a flesh-and-blood woman with human foibles and weaknesses, as well as great strengths and ambitions.Newly updated and published to celebrate Madonna's fiftieth birthday, this paperback edition covers the last six years in the star's life, including her self-imposed exile from America and adoption controversy, all told in J. Randy Taraborrelli's wonderful trademark style. 'Makes her more, not less, fascinating' - Lynn Barber, "Daily Telegraph". 'Makes for a great read...This is the Madonna biography' - "Mirror".
