The new Princess of Wales has revealed the heartwarming comment her youngest son made after learning his great-grandmother had passed away.
On Saturday (September 10), the new Prince and Princess of Wales were joined by Prince Harry and Meghan Markle as they took the time to greet well-wishers and observe the flowers and tributes left outside Windsor Castle in honor of the late queen.
Pictures and videos show the two brothers and their wives shaking hands and hugging members of the public, as the nation continues its period of mourning following Queen Elizabeth II's death on Thursday, September 8.
Cameras captured the moment Princess Catherine greeted a group of children who turned out on the Long Walk to pay their respects.
Princess Catherine could be seen becoming teary-eyed as she recalled what her youngest son - four-year-old Prince Louis - told her after he learned of his great-grandmother's death.
The princess told the children: "My little Louis, who's just so sweet, he said, 'mommy don't worry, because she's now with great grandpa'" - referring to Queen Elizabeth's late husband, Prince Philip, who died at the age of 99 in April last year.
Watch the moment below:One well-wisher who witnessed the conversation, 28-year-old Banita Ranow, later told the Daily Mail that the 40-year-old Princess of Wales appeared to be "welling up" as she recalled the story.
Ranow also spoke about what it was like seeing brothers Prince William and Prince Harry reunited, along with Princess Catherine and the Duchess of Sussex, describing the moment as "really nice".
Another video shared to social media shows Prince William greeting the same group of children.
The heir apparent can be seen holding a bouquet of flowers that had been handed to him, and shaking the hands of each of the children.
As they pay their respects, he tells them, "Thank you so much, guys" and "Thank all of you for coming, really appreciate it."
In his first national address as the new monarch, King Charles III announced on Friday that his eldest son, William, would become the new Prince of Wales, with wife Catherine becoming the new Princess of Wales.
"With Catherine beside him, our new Prince and Princess of Wales will, I know, continue to inspire and lead our national conversations, helping to bring the marginal to the center ground where vital help can be given," the new king declared.
Speaking about his youngest son and daughter-in-law Meghan, King Charles III said: "I express my love for Prince Harry and Meghan as they continue to build their lives overseas."
