Princess Diana would "light up" when she would talk about her sons.
The British royal is the mother of Princes William and Harry, and according to her friend Cleo Rocos, Diana would relish the opportunity to discuss her children.
The actress said: "She would light up when she would talk about the boys. She would say, ‘Harry has been mischievous,’ or told us how she loved going down to the kitchen with the boys at the Palace where the chefs would make extra biscuits and fudge for them."
The comedy actress also said she looks back on her time with the Princess with fondness.
She told Hello! magazine: "Just the thought of those times make me laugh. And if I wanted to stress anything about her to her boys, I would tell them, ‘If she wasn’t your mother, she would be just the sort of person you would love to hang out with.’ Diana was a joy – and she loved life."
Earlier this week, Prince William admitted he wishes his mother could have met his wife and watched his children grow up.
Diana died in a car crash in Paris, France, in 1997, when the Prince was just 15 years old.
William – who has Prince George, three, and Princess Charlotte, two, with his wife, the Duchess of Cambridge – said: "I would like to have had her advice. I would love her to have met Catherine and to have seen the children grow up. It makes me sad that she won’t, that they will never know her."
