Newsweek magazine's latest cover shows a computer-generated image of what Princess Diana might have looked like now at age 50, walking with Kate Middleton, who just married her oldest son, Prince William.

The accompanying article was written by Diana biographer and Newsweek editor-in-chief Tina Brown.

The issue also features an imagined Facebook page for Diana -- who would have turned 50 on Friday (July 1st) -- and a slideshow comparing the fashion styles of Diana and Middleton.

Some critics have called the Diana at 50 cover creepy or shocking, but Brown said in a statement yesterday (June 28th), 'We wanted to bring the memory of Diana alive in a vivid image that transcends time and reflects my piece.'
