Prince Harry’s biggest fan, Daphne Dunne, has died at the age of 99. 

Dunne passed away from pneumonia on Monday after being in the hospital.

“She was a truly special lady who will be greatly missed by so many. The simple act of stopping Daphne in the street and holding her hand meant more to Daphne than anyone could ever imagine,” a message on her Instagram read. “We, her family, would like to thank everyone for the love and support they showed Daphne.”

Dunne has just celebrated her birthday last week, and she had received a card from Prince Harry and wife Meghan wishing her a happy birthday.

“Congratulations on reaching this important and impressive milestone before your centenary year next year. Happy birthday, Daphne," the message read in part. 

The war widow first met Harry in 2015 when she watched as he walked outside of Sydney Opera House. In 2017, she was greeted by him again in Australia as he was visiting to help plan the Invictus Games. Harry walked up to her with a big smile and open arms.

In October 2018, she talked with Harry and met Meghan when the couple visited Sydney. Dunne congratulated the two on Meghan's pregnancy and said it was “just what Harry needs.” She added: "Congratulations, I think that’s marvelous."

Meghan told Dunne during the encounter, “Hopefully next time we see you we’ll have a little one with us.”

A source told People that the royal family was "deeply saddened" by Dunne's passing.
