There is NOTHING we enjoy more than watching the royal children having a moment of cheekiness on the balcony during Trooping the Colour - and this year it was little Savannah Phillips who definitely stole the show. But now an unearthed photograph from the 1990 Trooping the Colour has revealed that an adorable Prince Harry performed this little trick nearly 30 years ago! And the royal whose mouth he was covering? It's none other than his cousin Princess Beatrice!
Because we love these precious moments of mini-royal naughtiness so much, we've pulled together all the photraphs of the Queen's grandchildren and great-grandchildren, who can't help getting the hump or sticking their tongues out just as thousands of people tune in to watch the celebrations on TV.
Spoiler alert - Prince Harry has a starring role!
