Princess Diana would have turned 50, if she were alive, on July 1, 2011. The Newsweek July 4 issue features the image of an aged Diana (done digitally), along with her daughter-in-law Catherine Middleton.

The magazine’s editor-in-chief Tina Brown has also conjured up the life of the late Princess if she had survived the fatal accident of 1997.

According to Brown, who is also Diana’s biographer, Diana by now would have 10 million followers on Twitter and would have dumped Dodi Al-Fayed, who died with her in the accident.

Diana, who was a fashion icon, “would have gone the J.Crew and Galliano route à la Michelle Obama, always knowing how to mix the casual with the glam,” Brown writes imagining what Diana’s latest fashion stance might have been.

“There is no doubt she would have kept her chin taut with strategic Botox shots and her bare arms buff from the gym,” she added.

Predicting Diana’s personal life, Brown believes that she would have remarried at least twice, but “her best male friend in later years would have been, poignantly, her reviled first husband.”

Diana would have befriended Camilla and would have found peace in her sons, William and Harry, the Newsweek editor said.

To keep up her relationship with Kate Middleton as her daughter-in-law, “Diana would have had to adjust to a broadening of the limelight,” she said, adding that “the rising public adoration of Kate would have afforded Diana some tricky moments.”

Brown said she missed Diana’s star power when it comes to matters like disaster relief.

“In the world disasters of the last few years—9/11, the tsunamis, the Pakistan earthquake, Hurricane Katrina—you know Diana would have been first at the scene in a hard hat with a camera crew. She would have kept her spotlight trained on individual sufferers whom she’d continued to visit and care for and touch.”
