Prince Louis had comforting words to share following the death of Queen Elizabeth II, according to his mother, Kate Middleton.
Speaking with members of the public outside of Windsor Castle during an appearance alongside Prince William, Prince Harry, and Meghan Markle, the Princess of Wales shared the reaction her youngest son had to the news of the Queen's death on Thursday.
The moment was captured on video and shared by @magsmay1 via TikTok on Saturday, which had over 1.9 million views as of Sunday. Speaking to Insider, the TikToker said the clip was taken by her daughter, Nicole Anna Gumienny, who joined her from Hampshire, England, to see the royals at Windsor.
"My little Louis is just so sweet," Middleton can be heard telling the crowd about how he handled hearing of the Queen's death in the clip. "He was like, 'Mummy, don't worry. She's now with great-grandpa.'"
Gumienny told Insider that she was honored to meet the royals during an emotional moment for their family. "When Kate was telling the story you could feel the emotion," she said. "My eyes started watering when she talked about her Prince Louise saying that the Queen is now with great grandpa."
Rebecca English, the royal editor at the Daily Mail, also tweeted on Saturday that one well-wisher called Banita Ranow said Middleton shared the story with a group of children at Windsor.
"Ms Ranow said Kate was 'welling up' as she spoke," English wrote.
Louis, 4, referenced Prince Philip - his great-grandfather - who died at the age of 99 in April 2021. He and Queen Elizabeth II were married for 73 years and he remains the longest-serving British consort in history.
Louis's words echoed some of the final remarks made by Charles III in his first speech as king on Friday.
"To my darling Mama, as you begin your last great journey to join my dear late Papa, I want simply to say this: thank you," Charles, 73, said.
Louis is one of 10 great-grandchildren left behind by Queen Elizabeth II. The pair shared several memorable moments together, including some funny ones from the Platinum Jubilee in June.
During the Trooping the Colour, Louis stood beside his great-grandmother and didn't hold back on his reactions to the pageantry and celebrations, held in honor of the monarch's 70-year anniversary on the throne.
Other photos from the day showed the pair interacting with each other, and the Queen smiling at one of her youngest family members.
