If the late princess were alive, she'd be 50 this month. And with Kate Middleton off to Canada on Thursday (!!!), Kate Middleton still the most interesting story in the world to droves of people, and Newsweek crawling back from a near-death experience, editor Tina Brown's cover story about what life would be like for Diana today is just what the magazine needs and the world wants. Brown, author of a book about Diana, writes that Diana would have been worried about her "rivals," such as Queen Rania of Jordan, seeing her "beauty, youth, and social conscience as a triple threat that should be watched." As for Carla Bruni, "after some initial competitiveness ... she’d have probably bonded with her at the G20 dinner over ways to dodge Berlusconi."

Kate also would have posed a threat, initially:

The rising public adoration of Kate would have afforded Diana some tricky moments. Pleased, yes. But, like Frances Shand Kydd—who, days before Diana’s wedding, suddenly burst out, “I have good long legs, like my daughter”—Diana would have had to adjust to a broadening of the limelight. Her edge over Kate, of course, was her own epic of princessly suffering, which would always make Diana’s story more interesting. (“Happily ever after” will never have the same allure to the press as “It all went horribly wrong.”) Diana, rejoicing in her flawless Spencer pedigree, would have positioned herself as a firm defender of the Middletons against the palace snobs and ostentatiously made Carole Middleton, Kate’s dynamic mother, her new BFF.

Brown decides that Diana would have "found peace" by now. Also, she wouldn't have found herself creepily, artificially aged on the cover of Newsweek. Check out the reverse retouching (now what if that become a "thing"?) in a bigger shot of the cover.
