"25 Years Later: Princess Diana Remembered," a special tribute episode of Access Hollywood, will air Aug. 31 to honor the late royal and her legacy on the 25th anniversary of her death. In a preview of the episode, Access contributor and consultant Paul Burrell, who was Diana's personal butler and close confidant, recalls the moment he first saw Prince William and Prince Harry at Kensington Palace after their mom's passing. "Harry ran towards me, hugged me, cried, soaked my shirt wet with tears. I said to him, 'C'mon, let's go for a little walk around,'" he recalled, adding he then suggested the prince take an item of his mom's with them to give him "comfort." "Harry took a hairbrush with his mother's hair still in it," he said.
