Several stories about Diana’s mischievous antics have been made public over the years, but one story that rises above all others is the tradition she started when it came to buying her friends' children presents.
And in tribute to the late princess, her friends are carrying on the cheeky game with her grandchildren - but the Duke and Duchess of Cambridge might not be overly impressed.
Pychotherapist Julia Samuel was a close friend of the late Princess of Wales after meeting her at a dinner party and remained close with her family after her death. In 2013, Kate and William made her Prince George's Godmother.
Speaking on the How to Fail with Elizabeth Day podcast, she revealed: “[George] is amazing. He's funny and feisty and cheeky and God she [Diana] would have loved him so much. That is heartbreaking for all of them.”
She added that she continues a tradition started by Diana, who was godmother to her own son, revealing: “So I do to George what she did to us which is give impossible toys which are really noisy, take a lot of making.”
She explained: “I come in slightly tipped by the size of the present that William then has to spend days putting together.
“And then put all the machinery together and it makes awful tooting noises and lights flashing and all of that. That makes me laugh and it makes George laugh.”
Julia is one of seven godparents for Prince George, and was a touching acknowledgement of William’s late mother.
Prince George was christened in the Chapel Royal of St James’s Palace on October 23, 2013 and is very lucky to have four godfathers and three godmothers. The chosen recipients are all close to The Duke and Duchess of Cambridge and include everyone from The Duke of Westminster to Zara Tindall.

This special tradition isn't the only thing that keeps Diana close with her grandchildren. It is known that Prince William and Kate make their three children write thank you notes to anyone who has helped them - in the exact same way that Diana would make her two son's do.
The late royal is widely credited in books, films and the media as being an excellent mother Princes William and Harry. She often took them to private charity visits and on normal days out as she wanted them to live without the restrictions of strict royal protocol.
Her biographer, Andrew Morton said: “She took the young royals with her on her private charity visits from a young age… One of the reasons was she didn't want the boys to grow up thinking the whole world was 4x4 Range Rovers, shotguns and nannies.”
One of her best habits - and one that has been carried on by William with his own children - was getting her sons to write thank you notes to anyone who helped them.
A source explained: “[William and Kate] have developed this brilliant knack of letting as much as they can seem spontaneous and that’s how the children see it. Table manners, thank you letters, little courtesies are being drilled into the children so they become automatic.”
