The magazine's editor Tina Brown, who wrote a book about Princess Diana, pens an article about what Princess Diana's life would be like now if she were still alive.

“Remarriage? At least two, I suspect, on both sides of the Atlantic,” Brown writes.

She’d be a power player at Davos and the Clinton Global Initiative; have collected record-breaking damages in the News of the World phone-hacking scandal; and even reconciled with Prince Charles. She’d also have had to learn how to share the spotlight with Kate Middleton.

“Diana, rejoicing in her flawless Spencer pedigree, would have positioned herself as a firm defender of the Middletons against the palace snobs,” Brown writes.

Princess Diana's son, Prince William, married Catherine on April 29.
