Now, reports say Prince Harry has been reaching out to his mother's close friends and family for content for the documentary, which is expected to be released on the 30th anniversary of Diana's death next year.

An insider told Woman's Day, "William’s bracing for more too now that Harry and Meghan are forging ahead with their Diana documentary. 

"He’s used to people mining his mum’s existence for money and clout, but with Harry in charge it’s way too close to home."

The Prince of Wales is not only worried about how his mother's legacy will be affected by Harry's film but also its impact on his father, who is undergoing cancer treatment. 

The source shared, "The King’s health is always top of his mind, and already this book has caused him so much unnecessary distress.
