Prince Harry honors mom Princess Diana with flowers at her grave

While  Prince Harry  now resides in the United States, he still observed the UK’s Mother’s Day on Sunday, March 14. A spokesperson for the Duke of Sussex confirmed to HOLA! USA’s sister brand HELLO! that the California-based royal arranged for flowers to be laid at his mom  Princess Diana ’s grave at the Althorp Estate in Northamptonshire.

 Meghan Markle ’s husband was 12 years old when his mother died in 1997. Following her funeral service, the Princess of Wales was “buried in sanctified ground on an island in the centre of an ornamental lake” at Althorp.

Harry wasn't the only member of the British royal family who honored Princess Diana on Sunday.  Prince William  and  Kate Middleton ’s children— Prince George ,  Princess Charlotte  and  Prince Louis —also paid tribute to their late “Granny Diana” on March 14. Kensington Palace shared photos of the Mother’s Day cards that the Duke and Duchess of Cambridge’s kids made.

“Dear Granny Diana, Happy Happy Mother’s Day. I love you very much and think of you always. Sending lots of love from George,” Prince George wrote in his card, while Charlotte penned to her Granny Diana, “I am thinking of you on Mother’s Day. I love you very much. Papa is missing you. Lots of love Charlotte.”

Kensington Palace captioned the moving post, “This year Mother’s Day will be different once again. Many of us will be apart from our loved ones, but looking forward to a time in the not too distant future when we can give our mother a hug again. But for those experiencing bereavement, today may be particularly challenging. Each year on Mother’s Day, George, Charlotte and Louis make cards remembering their Granny, Diana, for William. Whatever your circumstances, we are thinking of you this Mother’s Day 💐.”

Aside from making cards for their late grandmother, George, Charlotte and Louis celebrated Mother’s Day with a homemade cake for their mom, Kate. The palace shared a photo of the dessert, as well as a vintage snapshot of the Duchess and her mother Carole Middleton, writing: “Celebrating two other special mothers today ❤️.”
