Prince George and Princess Charlotte are expected to join this year's Trooping the Colour. However, due to the event's cancellation, following the coronavirus outbreak in the U.K., the official celebration of Queen Elizabeth II's birthday is canceled.

It looks like fans still have to wait for another year before they see Prince George and Princess Charlotte officially join the royal carriage procession. As there will only be a small-scale celebration this year, it remains to be seen who will join Queen Elizabeth II to mark her official birthday commemoration.

Prince William and Kate Middleton's first two kids are deemed old enough to join the royal procession. However, with the event's cancellation, their appearance also gets canceled, People noted.

The kids had already appeared on the palace balcony during the Trooping the Color for the past years. Last year, their youngest brother, Prince Louis, also made his first balcony appearance, looking cute as he waved to the public.

Some members of the royal family usually ride horses in the parade, like Prince Charles and Prince William, wearing their full military regalia, along with large bearskin hats. Others also take part in the ceremony by riding carriages. In 2019, Kate Middleton, Camilla, Duchess of Cornwall, Meghan Markle, and Prince Harry rode together before they joined the kids on the palace balcony.

According to Express, when the Duke of Cambridge made his first ride on the royal carriage in 1987, he was about to turn five years old. He was alongside his father, the Prince of Wales, mother, Princess Diana, and the Queen Mother.

Prince Harry, too, was almost five when he took part in his first procession in 1989. As Prince George is now six and Princess Charlotte is already five, it is supposed to be the perfect time for them to do so. 

This year, the official celebration of Queen Elizabeth's birthday will be heavily scaled down. It has been a usual practice for people to gather along The Mall and outside the Buckingham Palace to watch the royals' procession.

The royal family will then gather on the balcony to watch the fly-past and greet the people. However, things will be different today due to COVID-19 pandemic.

A miniature celebration will be held at Windsor Castle, where Queen Elizabeth is currently self-isolating, along with her husband, Prince Philip. It remains to be seen who among the royal family members will join Her Majesty to mark the event.

Prince George and Princess Charlotte were supposed to make their first royal procession last year, but their mother, Kate Middleton, rode along with Prince Harry, Meghan Markle, and Camilla instead. Hence, fans may get to see them riding the royal carriage when everything goes back to normal next year.
