- Princess Charlotte, the four-year-old daughter of Prince William and Kate Middleton, was seen sticking her tongue at viewers during The King's Cup regatta today.
- Shocked by the gesture, Duchess Kate quickly pulled Charlotte away from the window.
- Prince George and Carole Middleton, Kate's mother, were also seen with Charlotte.
Princess Charlotte is a total royal sweetheart, but she's got a bit of sass too. Remember when she told photographers they weren't invited to Prince Louis's christening after party? (Okay, it was more like an intimate family gathering after the religious ceremony, but she still essentially played bouncer and told the paps that they couldn't hang.)
Today, the four-year-old princess yet again showed her cheeky side while accompanying family at The King's Cup regatta. After the sailing race, mom Kate Middleton goaded her to wave to onlookers, but Charlotte had other ideas. She peered out from the window and stuck her tongue out at the crowd, sending her royal mother into a minor freakout.

Charlotte gives the crowd a silly greeting.

Kate laughs over her daughter’s antics.
Watch the whole moment play out in the video below.
The fourth in line for the throne could've easily given the audience a proper greeting if she wanted to, but she's already shown us that. 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. This time, however, she went the playful route.
Charlotte was later joined by her older brother, Prince George, and the silly faces continued. Kate's mother, Carole Middleton, was also spotted with the family.

The Cambridge siblings were first spotted on a boat with their grandfather, Michael Middleton, as their parents competed in the charity sailing event. It doesn't seem like their one-year-old brother Prince Louis was in attendance, but if he was, he'd have the best silly faces of them all.
