The Queen's great-granddaughter has certainly earned a reputation for being our cheekiest young royal over the years - particularly at 2018's Trooping the Colour, when she stole the show by teasing her cousins Prince George and Princess Charlotte, and pulling some hilarious faces!
Savannah - who is the Her Majesty's oldest great grandchild - also showed just how sassy she is, as Twitter went into meltdown after she put her hand over George's mouth to keep him quiet. Take a look through all the best moments Savannah made her mark during the annual celebrations - and a few extra for luck!

Between them, Charlotte was soon cheered up and back to watching the planes.
