Royal Children's Roles at Coronation Revealed as Louis Takes Center Stage.

Prince George, Princess Charlotte, and Prince Louis will join the grand carriage procession back to Buckingham Palace after their grandpa's Coronation. The King and Queen will travel in the 261-year-old Gold State Coach, followed by three carriages carrying working members of the Royal Family. Louis, who was the standout star of his great-grandmother's Platinum Jubilee celebrations last year, will be too young to attend tomorrow's concert in Windsor. Meanwhile, Queen Consort Camilla kept a low profile as she prepared for today's historic occasion.
