Princess Charlotte and Prince Harry shared a sweet moment together at the Queen's committal service

As Queen Elizabeth II was laid to rest yesterday (19 September), Prince Harry and Princess Charlotte seemed to share a sweet moment during her committal service.

The sweet exchange did not go unnoticed by royal fans on social media, who were quick to praise Prince Harry for his actions.

One wrote: "Harry and Charlotte sharing a little moment while the choir sings. So sweet."

"Maybe he saw Diana in her," speculated a second. "She looked so pretty."

Alongside a heart emoji, a third added: "Cute little smile between Harry and little Charlotte." 

Princess Charlotte was joined at the service by her older brother, Prince George, nine, who is now second in line to the throne.

The Queen was laid to rest in the historic Windsor chapel alongside her husband, Prince Philip, the Duke of Edinburgh.

Her parents, George VI and the Queen Mother, as well as her sister, Princess Margaret, all rest there too, alongside other historic royals including Henry VIII and his favourite wife, Jane Seymour.

The Princess of Wales has since opened up about her young children's reactions to the death of their great-grandmother, revealing that Prince George is is 'sort of now realising how important his great-grandmother was and what is going on.'

However, because Prince Louis is so young, he does not yet understand the finality of death or what has happened to the Queen.

The Princess of Wales revealed: "The younger one is now asking questions like, 'do you think we can still play these games when we go to Balmoral?' and things like that, because she's not going to be there."

However, she did tell one royal well-wisher that the young prince had a sweet reaction too and said in response to the Queen's death: "At least Grannie is with Great Grandpa now."

The Queen passed away on 8 September at her home in Balmoral, Scotland, at the age of 96, after reigning for over 70 years.

She celebrated her Platinum Jubilee this summer and was Britain's longest-reigning monarch, surpassing a title that was previously held by Queen Victoria, who sat on the throne for over 63 years.
