FILE - In this file photo dated April 13, 1992, Princess Diana leaves the Natural History Museum after viewing a dinosaur exhibition with her sons Prince Harry, left, and Prince William. The Princes William and Harry grew up together, supported each other after their mother’s untimely death and worked side-by-side as they began their royal duties, two brothers seemingly bonded for life, but those links now seem painfully strained. On Thursday July 1, 2021, William and Harry will together unveil a statue of their mother, Princess Diana, on what would have been her 60th birthday. (AP Photo/Gill Allen, FILE )
