Kate took two out of three of the little royals to the Maserati Royal Charity Polo Trophy at Beaufort Polo Club to raise funds for the Royal Marsden cancer hospital and Centrepoint, a homelessness charity.
Savannah Phillips, the unsung hero of Trooping the Colour who hilariously silenced her cousin Prince George's mouth by putting her hand over his mouth, was also in attendance and she was up to her usual antics.
George, dressed in beige shorts and a navy t-shirt, was pictured playing with a toy gun, toy knife and handcuffs.
While Charlotte left us gushing over how adorable she looked even while crying, after she fell from the bench on the Buckingham Palace's balcony, one can not ignore Prince George's naughty antics.
Twitter account Elegantroyals added: 'This was the only disappointing thing about today's polo match. Both William and his brother will participate in many charitable polo matches throughout the summer - which means there will be plenty more opportunities to see Kate Middleton while she's still on official leave!
The moment has been captured, with people going gaga over this royal Tow Sawyer-like child, also giving a flawless throwback to the time Prince Harry shared a similar moment with Princess Beatrice. The little ones were clearly excited to be out and about after attending Queen Elizabeth's more formal Trooping the Colour the day before.
However, many also rushed to defend Prince George and his parents, pointing out that the young royal will one day be Commander-in-Chief of the British Armed Forces.
