Prince Charles, 5, is the eldest son of Grand Duke Guillaume, 43, and Grand Duchess Stéphanie, 41, and big brother to Prince François, 2. On October 3, a historic moment took place in Luxembourg when Grand Duke Henri officially stepped down after 25 years on the throne, making way for his son, Guillaume, in a voluntary abdication ceremony at the Grand Ducal Palace in Luxembourg City.

While the transition marked a major moment for the royal family, it was young Prince Charles who truly stole the show.

According to royal fan blog Gert’s Royals, cameras caught the little prince fiddling with his shoelaces during the ceremony—so much so that his grandmother, Grand Duchess Maria Teresa, had to step in and help re-tie them.
