Princess Charlotte falls at the Trooping the Colour ceremony -- but Duchess Kate acts fast

Princess Charlotte took a tumble at Saturday's annual Trooping the Colour ceremony -- but luckily, mom Duchess Kate was able to swoop in and save the day.

Joined by brother George and cousin Savannah Phillips, the three-year-old royal was standing on Buckingham Palace's balcony to watch the Royal Air Force's jets fly past the crowds to mark Queen Elizabeth's 92nd birthday. The monarch also took the balcony alongside Prince Charles and Duchess Camilla, as well as Prince Harry and Duchess Meghan.

Charlotte seemed in relatively good spirits for most of the ceremony, showing off her little royal wave and clap. However, at one point, she slipped off the platform -- with some viewers believing she hit her head on the balcony's railing. The royal tot was visibly shaken, quickly turning to mom Duchess Kate for comfort.

Kate, dressed in Alexander Mcqueen, was quick to swoop Charlotte up in her arms and hold her for the rest of the traditional ceremony.

Brother George also had a viral moment of his own. It seems his chatting was too much for his cousin to handle, so Savannah covered the four-year-old's mouth with her hand as to "shush" him.

It was a weekend of festivities for the royal family. After Saturday's get together, Duchess Kate and clan (sans Prince Louis) supported Prince William at the annual Maserati Royal Charity Polo Trophy on Sunday. Charlotte, once again, stole the show with her adorable sunglasses and toddler antics -- which consisted of a few twirls and somersaults.
