The Prince and Princess of Wales are notoriously protective of Prince George, Princess Charlotte and Prince Louis' privacy - but they do offer small updates on how the young trio are getting on.
From Prince William passing on his daughter's message to the England Lionesses that she is "very good in goal" to Kate revealing what Louis said after the late Queen had passed away, there are a number of stories to choose from.
Other stories that have emerged about the young royals have previously come from celebrity interactions with Prince William and Kate.
Oscar Winner Rami Malek revealed one such story about the time he offered his babysitting services to the couple.
During an appearance on Jimmy Kimmel's talk show, the actor recalled a conversation he had with the Princess of Wales at the Baftas in 2019, where he took home the best actor prize for his role as Freddie Mercury in Bohemian Rhapsody.

Making an appearance on the show, the actor explained: "The funniest thing about that was, I said, 'If you ever need a day off, some time off, I’m back-up for you.'
"She's like, 'What do you mean?' I go, 'I can babysit, you guys go out, have a good time.'"

The actor continued: "What's fascinating is, they work so hard to get to know everybody – who’s done whatever film they’ve done, their past films'.
"You can see they’ve done their homework. And I just looked at Princess Kate at one point, and I said, 'This must be exhausting.' And she said, 'Why?'
Malek then mentioned Prince Louis' birth and asked the Princess how she was doing: "[I asked,] 'You just had a baby, right?' I think she was taken aback.
"She said, 'How are you doing?' [I’m like,] 'No, how are you?' And in the most regal, elegant way, she gave me a look. But you can tell. Imagine, you’re dressed to the nines, have to talk to all these actors.
"They're so careful. But it was so cool. I think I caught her off guard for a second. And, you know, had that look of – in the most elegant, professional, royal way – 'Yes, it's a lot, having a kid.'"
The Prince and Princess of Wales clearly didn't mind Malek's line of questioning as Prince William invited him to be one of the celebrity hosts at last year's Earthshot Prize Awards ceremony in Boston.

"I was up at 4am doing my hair. That's early, even for me. I was up, dressed and waiting by the door by 7am. Jim took pictures of me in the car. You can see rays of happiness shooting out of my face. I love Kate Middleton that much.
"And she did not disappoint! She was just lovely and warm, elegant and composed. She also told a joke, and I immediately fell under her spell. She's just as magnificent as she seems to be. She's a very compassionate, socially conscious, deeply caring person. It takes a very special person to decide to commit to that kind of life."
