In the joyous photo, the royal looks relaxed and comfortable in a baggy sweatshirt, laughing with her eyes squeezed shut.
“Diana as I remember her,” Moncktoncaptioned the rare image. “Not enough is written about her sense of fun and zest for life. Friend and wonderful godmother to Domenica. RIP.”
Monckton was a close friend and confidante to the late Princess of Wales — who was the godmother to Monckton’s daughter, Domenica. When Domenica was was born with Down syndrome in 1995, Diana provided the ultimate support.
“She said, ‘You just have to believe in her,’ ” the British jewelry executive, who met Diana through a mutual friend,told PEOPLE in 2016. “She said, ‘Believe in her, love her and I’ll be there every step of the way.’ She already had that vision of what Domenica could become, which I simply couldn’t see.”
