Little captain Prince George shows off his gap-toothed smile while Princess Charlotte gets sassy

The royal cutie and his little sister took to the high seas to cheer on their parents at the King's Cup Regatta.

Losing your baby teeth is a big deal when you’re a kid, and Prince George has shed more than a few lately—for all the world to see! Just weeks after new photos were released to celebrate his sixth birthday, it seems the future king has said so long to both his front teeth, and we have to say that his gap-toothed smile is everything. The Cambridge kids were the cutest surprise spectators at the King’s Cup Regatta on Thursday, where George looked particularly apropos (and adorable!) in a captain’s hat while Princess Charlotte showed her sassy side by sticking out her tongue.

The little royal looked too cute in a preppy striped polo shirt and life jacket, topped off with his oversized sailor’s hat.

Four-year-old Princess Charlotte was also spotted with her big brother and their grandparents, Carole and Michael Middleton, looking sweet as can be in a striped Ralph Lauren Kids dress with peter pan collar. Later, she joined her mom to watch the awards ceremony and, when told to wave, decided to serve up some of her famous ‘tude instead (we’re here for it!). Sadly, we didn’t get a glimpse of one-year-old Prince Louis, who was likely back home on terra firma with his nanny.

Check out the pics—we can’t handle!

Here’s Charlotte’s silly face caught on video:

The Cambridges were fresh off a two-week vacation on the uber-private Caribbean island of Mustique and looked tanned and relaxed. The family feted Prince George’s birthday while they were away, and we’re betting that meant lots of virgin cocktails on the beach! But Prince William and Kate were all too happy to make a rare summer appearance for the charities they love.

It’s been a fun school break for George and Charlotte, who have reportedly been whipping around the grounds of Kensington Palace on their scooters (George in a Union Jack helmet), and the little prince has also been getting tennis lessons from none other than Roger Federer—who was pretty impressed with his swing. The dog days of summer will likely bring a trip to Balmoral to visit their great-grandparents, the Queen and Prince Philip, before George heads back to London’s Thomas’s Battersea school, this year with his little sister in tow.
