Princess Charlotte has had her fair share of cheeky moments. Who could forget the time she told off photographers that weren't invited to Prince Louis' christening. Now, the sassy four-year-old has struck again while accompanying family at The King's Cup Regatta.
After the sailing race, mum Kate Middleton goaded her to wave to onlookers, but Charlotte had something else in mind. She peered out from the window and stuck her tongue out at the crowd, leaving mum Kate having a minor freakout.
Watch the whole moment play out in the video below.
Charlotte has already shown she can nail the perfect royal wave. She previously stole the show at events like Trooping the Colour and Prince Harry and Meghan Markle's royal wedding with a flawless royal wave.
Charlotte was later joined by her older brother, Prince George.
