Cheeky Princess Charlotte goes viral for silly move at King's Cup regatta

Cheeky Charlotte is back!

The adorable 4-year-old tot joined big brother Prince George (who showed off his new toothless smile!) and grandparents Michael and Carole Middleton to cheer on her parents at the inaugural King's Cup Regatta. The racing event on Thursday, held at Cowes, Isle of Wight, was organized by the Duke and Duchess of Cambridge to raise money for their various patronages.

Following the race, the Duchess of Cambridge joined the rest of her family for the King's Cup trophy presentation ceremony.. However, the celebration was quickly overshadowed by naughty Charlotte, who instead of waving to onlookers, gave them a slew of funny faces and stuck out her tongue.

Kate can be seen laughing in the background while trying to encourage her daughter to behave.

This isn't the first time the young royal got silly for the public. The royal made the same face at the RAF 100 event and again at Prince Harry's royal wedding in May 2018.
