King's Cup Regatta on the Isle of Wight is a big day for the Duke & Duchess of Cambridge.
The royals, Kate Middleton and Prince William, hosted the regatta and even took to the water themselves to compete against each other.
Unfortunately, it was Kate who lost and received the wooden spoon, but it seems the Duke & Duchess' two eldest children didn't care to much for the exciting race, instead stealing the show with their cheeky and fun behavior.
Prince George was spotted hanging out in the cockpit of one of the boats, sporting a captain's hat and lifejacket.
He grinned an adorable gappy grin, and smiled for the camera.
Princess Charlotte however made sure she was not to be outdone by her older brother and had fun sticking her tongue out to photographers as the Duchess tried to reign her in.
