Her Majesty may be the Queen of the United Kingdom and Commonwealth, but to a handful of her children, she is just "Gungans."

Her Majesty's 12 great-grandchildren call her that, and when that home is Windsor Castle (or Buckingham Palace, Balmoral Castle, or Sandringham House), the phrase "going to grandma's house" takes on a whole new meaning. The Mirror and The Duke of Cambridge According to Mrs. Duke, the Queen has a sweet habit of leaving "special treats" for her great-grandchildren to stay, "to show her love" for them.

"Whenever we go to stay over, the Queen always leaves a little gift or something in their room, and that alone shows her love for her family," Kate said in the ITV documentary Our Queen at 90.

And while the Queen probably doesn't play favorites when it comes to her great-grandchildren, Kate says Her Majesty has a special fondness for Princess Charlotte (Charlotte, incidentally, is the Queen's doppelganger): "The Queen was really thrilled that this is a girl," Kate says. 'I think Princess Charlotte was one of our first visitors as soon as we got back to Kensington. I think the Queen is very fond of Charlotte. She is always looking at what Charlotte is doing."

In the same documentary, Kate praised the Queen's "thoughtfulness, really, and care in taking care of everybody."

And speaking of the Queen's great-grandchildren, today 10 of the Queen's 12 great-grandchildren will be participating in the Royal Windsor Horse Show's "Gallop Through History" carriage procession, which the Queen is expected to join. (Archie and Lili are still in California before heading to the Platinum Jubilee next month, so their two great-grandchildren will not be attending. Lady Louise, the Queen's youngest granddaughter, will be driving the carriage as a touching tribute, mimicking her late grandfather, Prince Philip.) The great-grandchildren have been seen practicing for weeks to appear in this meaningful scene.
