WATCH: Young royals steal the show at king's coronation
Fresh off stealing the show at last year's Platinum Jubilee, Prince Louis had his turn in the spotlight again Saturday at his grandfather's coronation.
Louis, who turned 5 last month, joined his family -- parents Prince William and Kate and siblings Prince George, 9, and Princess Charlotte, 8 -- at the coronation of King Charles III and Queen Camilla.
The nearly five hours of events, including the coronation service at Westminster Abbey and a procession, provided Louis plenty of time to show off his personality once again.

During the procession from Westminster Abbey to Buckingham Palace after the service, Louis got a window seat in his family's carriage, which allowed him to wave and even put his nose up to the window for a closer look.

Prior to Saturday's coronation, Kate shared her honest expectation when a well-wisher asked her whether Louis would be on his best behavior for his grandfather's historic day.
"I hope so," Kate said, according to a video shared on social media. "You never quite know with kids."
