Prince William and Catherine's three children made their red carpet debut Friday for a Christmas show in London. According to Kensington Palace, the performance of The National Lottery's Pantoland at The Palladium was held to honor pandemic workers.
It was the first time all three children — Prince George, 7, Princess Charlotte, 5, and Prince Louis, 2 — have appeared together at a public event. William and Catherine put on masks once inside the theater, according to Entertainment Tonight.
William addressed the audience before the show began, saying, "you have given your absolute all this year, and made remarkable sacrifices," according to the Associated Press.
Kensington Palace said William and Catherine during intermission addressed a "small number of key worker families to hear more about their experiences over the past year."
