The media attention started early for their mother.
Thousands of people lined the embankment as the cortege, with police escort, travelled up the M1 following an emotional funeral service at Westminster Abbey.
In the 1990s Diana often appeared in power suits and more casual outfits for her charity work. It was one of the hardest things I've ever done. "I said, Mommy, Mommy, this can't be true, maybe it's a radio play, or a false report".
William described himself as "sad" that Diana would never meet his wife, Princess Kate, and their children, 4-year-old Prince George and 2-year-old Princess Charlotte. Liz's advice is to "acknowledge their pain and recognise they are vulnerable, ensuring they have a good level of support in all areas of their life at this time".
The then Bishop of Peterborough Ian Cundy played a significant part in her burial.
From frilly frocks to power suits, much of what Princess Diana wore has become the byword for the lavish extravagance of the '80s. "I remember her showing me ballet shoes she had been given and she was so proud of them", Prince William reminisced. Recently, the Daily Mail reported Diana's private secretary believed the princess was about to end her relationship with Dodi soon after their trip.
He added that she was 'a bit agitated'. She either visits Kensington Palace in London or the Spencer family estate in Althorp, not far from Birmingham, where Diana was buried. From the moment they arrived in the city they were hounded by photographers wanting to get their shot of the two.
The way the Prince's interact with the press continues to be a talking point today. "I can therefore wholeheartedly relate to the Mother's Day Campaign as I too have felt - and still feel - the emptiness on such a day as Mother's Day". His coach was Victoria's Gareth Rees. The outfit was dubbed the "Elvis dress" because it reminded many of Elvis Presley. To this day, the Kensington Palace in London, where she lived in the years that she was married to Prince Charles, is frequented by Diana's fans who lay bouquets and wreaths to mark her birthday and the anniversary of her death. And William and I know that, we've been told that numerous times by people that know that was the case.
"Nobody knew it was her, nobody had recognised her. As I approached, I saw there was a blonde person". Her obsession with Diana began in 1980, when Prince Charles announced his engagement to Diana.
Princess Diana was one of the best loved members of the Royal family. Life is altered as you know it, and not a day goes past without you thinking about the one you have lost.
