Earlier this week, Marie Claire reported on Princess Charlotte's four-word order to keep her brother Prince George in check, but George is not the only one Charlotte is keeping in check. At King Charles' coronation last month, Charlotte did the same thing to her brother Prince Louis.

As the Mirror reported, this time last year the Queen was celebrating her platinum jubilee.

Charlotte and Louis were in the carriage with their mother, Kate, George, and Camilla, then Duchess of Cornwall. The three Welsh children (then children of the Cambridge family) made their carriage debut at Trooping the Colour, and "the young royals beamed as they waved to their nearest and dearest and looked around at the horses participating in the monarch's official birthday celebration," the magazine reported.

Frankly, in a moment that probably gets talked about every year, Charlotte seemed unimpressed with her brother's enthusiastic waving. She was then seen telling him to stop and slapping his hand away," the Mirror reported. But Louis didn't seem too put off and kept smiling. (Incidentally, Louis was wearing a sailor-style top that his father Prince William wore at Trooping the Colour in 1985.) Later, Charlotte held her brother's hand and "supported him on this big stage," the magazine wrote.

Trooping the Colors will be held again this year on June 17 - the first time King Charles will participate as monarch. The King and William will ride horses, while other members of the royal family, including Kate and Camilla, will watch from carriages and the balcony of Buckingham Palace.
