On the cover is an image of an aging Diana superimposed on an image of Duchess Catherine. Tina Brown, editor-in-chief of Newsweek and Diana biographer, wrote the cover story, which includes an imaginary Facebook page maintained by the Princess. PEOPLE reports that Brown also predicts Diana would have moved to New York, indulged in Botox and engaged wholeheartedly in the social networking site, Twitter. "Diana would have been 50 this month," Brown added. "What would she have been like? Still great-looking: that's a given."
