Prince Charles turns the big 7-0 in November and to celebrate, Buckingham Palace are displaying a number of art pieces at the Prince and Patron show this summer, personally selected by Charlie himself.
And while we know there will be some stunning artwork on show, there's one photo that caught our attention.
This royal fan who goes by the Instagram name @teatimewiththecambridges has shared a previously unseen photograph of three generations of royals. In the photo, grandpa Prince Charles cradles one of his grandchildren in his arms, who we presume to be a sleeping Prince George or Princess Charlotte. Meanwhile doting dad Prince William crouches behind, that's three generations of royal cuteness!

That's not the only previously unseen photo of Prince George we've seen, this one from the Cambridge clan's 2016 Christmas card is exceptionally cute.
And it's clear Prince Charles loves being a grandfather. After Prince Louis was born, he and Duchess Camilla released a statement expressing their joy.
""We are both so pleased at the news. It is a great joy to have another grandchild, the only trouble is I don't know how I am going to keep up with them," he jested.
Prince Louis proved just how adorable he is in his christening photos, but Prince George and Princess Charlotte have had their fair share of photographic moments too. Take a look at some of their highlights below.
