Let's take a look at the monarch and her grandson's best moments together.
At the end of the Platinum Jubilee celebrations in June 2022, the Queen made a very brief appearance on the balcony of Buckingham Palace. She was joined by her heirs including Charles, William and George, and sweetly turned to her grandson to ask him about the Pageant which she had missed.
"Where were you sitting?" she asked William, to which he replied and pointed: "Over there, in the Royal Box." Following William's indications, the Queen went on to wave in the Royal Box's direction, where her daughter Princess Anne, granddaughters Zara Tindall, Princess Beatrice, and Princess Eugenie were sitting alongside their spouses and children, with the exception of baby Sienna, who was absent from the festivities.
