See All the Adorable Photos of George, Charlotte, Louis, and Baby Archie Cheering on Their Dads at a Polo Match

Today, Prince William and Prince Harry are participating in the King Power Royal Charity Polo Day, a charity polo event, to benefit their patronages. As expected, the royals had quite a fan club cheering them on from the sidelines at Billingbear Polo Club: Kate Middleton and Meghan Markle were on hand to support their husbands, and Kate brought along Prince George, Princess Charlotte, and Prince Louis for the day. And a very special surprise guest came: baby Archie! Meghan brought her son along for his very first polo match—and the little royal sweetly took in the match in his mother's arms.
