See Prince Louis Steal the Spotlight With Silly Faces at Trooping the Colour

The youngest son of Prince William and Kate Middleton couldn't help but cover his ears during the Platinum Jubilee flypast.

Prince Louis showed off his cheeky personality while standing next to Queen Elizabeth on the balcony at Thursday's Trooping the Colour. In a hilarious moment during the event, the 4-year-old couldn't help but cover his ears as aircrafts flew overhead.

Ahead of the celebration, George, Charlotte, and Louis made their carriage debut, greeting onlookers as they sat across from the Duchess of Cambridge and Camilla, Duchess of Cornwall. It was then when Louis was spotted wearing Prince William's adorable sailor suit from his childhood.

Thursday began the Platinum Jubilee celebration, which marks the monarch's 70 years on the throne. The festivities will continue through Sunday, which include a full-royal family gathering at Friday's Service of Thanksgiving in St. Paul’s Cathedral, a star-studded celebration taking place on Saturday night, and a Jubilee Lunch at The Oval in London among other events.

Ahead of the busy weekend, the Queen thanked well-wishers in an Instagram post, saying: "I know that many happy memories will be created at these festive occasions. I continue to be inspired by the goodwill shown to me, and hope that the coming days will provide an opportunity to reflect on all that has been achieved during the last seventy years, as we look to the future with confidence and enthusiasm."
