Kay said he spoke to the 36-year-old shortly before her death in 1997.

According to the outlet, Kay said Diana was very eager to embark on the next chapter of her life.

Harry previously recalled the last phone call he had with his mother in the ITV and HBO documentary "Our Mother Diana: Her Life and Legacy," which aired in 2017 to mark the 20th anniversary of her death.

The brothers admitted that their last phone with Diana was brief.

Princes William and Harry previously spoke out about their mother in a documentary titled ‘Our Mother Diana: Her Life and Legacy.’.

"If I’d known that that was the last time I was going to speak to my mother the things that I would – the things I would have said to her," said Harry, as quoted by People magazine.

"There’s not a day that William and I don’t wish that she was still around, and we wonder what kind of a mother she would be now, and what kind of a public role she would have, and what a difference she would be making," Harry added.
