See the adorable pics of Prince George and Princess Charlotte cheering on their parents at a charity regatta

The royal siblings looked like they were right at home on the water.

On Thursday the Duke and Duchess of Cambridge competed in the inaugural King's Cup regatta in Cowes on the Isle of Wight, and while they had plenty of fans cheering them on there were two very special additions to the crowd – Prince George and Princess Charlotte!
The two eldest Cambridge children joined their parents for the charity event, which saw them compete against each other and six others, to raise awareness and funds for eight of their royal patronages and Kate and William would have no doubt been delighted to have their children there.

Dressed for the nautical theme Prince George sported a captain's hat, blue-and-white striped shirt (and several missing front teeth!) while Princess Charlotte, four, wore a summery, Ralph Lauren blue-and-white striped dress, complete with a life-jacket, of course.

Keeping a careful eye on the youngsters was their grandparents, Mike and Carole Middleton and according to People, Prince Louis, one, was also on the island, however was likely in the care of the family's nanny Maria Borrallo.

The inaugural King's Cup regatta was originally scheduled for August 9th, however due to forecasted bad weather, the event was pulled forward a day.
The event saw Kate, William and six other notable UK celebs – Bear Grylls, actor John Bishop, footballer Fara Williams, TV presenter Dan Snow, radio personality Katie Thistleton and rower Helen Glover – compete against each other on separate vessels, each representing a charity.

The eight charities, all of which Kate and William are patrons of, included Child Bereavement UK, Centre Point, London's Air Ambulance Charity, Tusk, Action on Addiction, Place 2 Be, Anna Freud National Centre and the Early Years Programme, delivered by the Royal Foundation.
Bear Grylls' team who were competing for Tusk, took out first place, being awarded the historic King's Cup, while Kate's team unfortunately came in the final spot, with her hilariously being awarded a giant wooden spoon.

Thursday's event marks the first time we've seen the Cambridges in public since they jetted off to the private island of Mustique for the summer holidays, where they also celebrated Prince George's sixth birthday.
To mark the occasion Kensington Royal shared three gorgeous images of the future King, taken by the Duchess of Cambridge.

It's understood that the race marked an exception for Kate and William who are taking a break from royal engagements for the month of August.
The Queen is also on her summer holiday, arriving at Balmoral in Scotland earlier this week, a place which is known to be her favourite estate and one she holidayed to plenty of times with her family throughout the decades.
She marked her arrival in Scotland by inspecting the Balaklava Company and had everyone talking about her reunion with a notoriously mischievious pony called Cruachan IV, who is the mascot of the Royal Regiment of Scotland.
In 2017 the pony hilariously ate the Queen's posy of flowers to which she sternly told it to "go away", before telling the minder that "they always try to eat the flowers."
