King Charles could be set to gift Princess Catherine a priceless present for her 44th birthday today. The 77-year-old is said to be extremely fond of his daughter-in-law, who married his eldest son Prince William in 2011.

The much-loved royal will undoubtedly be made to feel extra special today, with William and their three children likely to shower her with many lavish gifts. As well as likely gifts presented to her from her fellow royals, the King will likely present her with an extra special gift. Former royal butler Grant Harrold recently spoke with Heart Bingo about what the King could gift to Catherine today.

He said: “It could be a hand-me-down from his mother. It could be something from his private collection of things that he likes to give family members… things that are sentimental to him.

“When he was Prince of Wales, he would give things that had the insignia on them, depending on who it was. It’s possible that he could do something like that.

“Or it might be something he’s advised from the Royal Collection, maybe something that’s a family heirloom that he’s allowed to pass on.

“You’ve got to remember, family heirlooms – a lot of the items do personally belong to the King, but some of them are not personally owned by the King, but they’re in the Royal Collection. He could still give something that remains in the Royal Collection.”

He also shared that the King may even host a party for the beloved royal tomorrow – or the family could hold a private dinner in Windsor. He predicted that it will be “more of an intimate family dinner” than any kind of large-scale party.

Mr Harrold said: “All royal birthdays are celebrated in some shape and form, even if the birthdays aren’t big celebrations,” Harrold said. “When I worked for the King, he would certainly have a private dinner. It wouldn’t be a big family gathering, it’d just be a private dinner.

“I can almost guarantee that the King will still host a birthday party for his daughter-in-law. It’s possible that it will be on the actual day of the birthday, unless William’s got something private arranged. There’ll be a celebration, and food-wise, she will be eating some of the things that she likes.”
