Dannii Minogue is one of the world's most enduring stars. She first appeared on television in the 1970s and has since been a soap actress, a pop singer, a model and a television presenter. More recently she has found a new level of fame and admiration as a popular judge on the hit reality television show the X Factor. Hers has been a life lived in the glare of publicity - unrelenting, even when her marriage to an Australian actor collapsed in its second year. And for much of her career she has had to live in the shadow of sister Kylie who she nursed through a brave fight against cancer. Now Dannii is undoubtedly an established figure in her own right. Chas Newkey-Burden - who has written bestselling biographies of Simon Cowell and Amy Winehouse - paints a revealing portrait of a restlessly creative woman who tirelessly re-invents herself to be endlessly fascinating and attractive.
