Sophie and the king attended the Royal Windsor Flower Show on Saturday

Royal watchers were left gushing over a touching moment between King Charles and his sister-in-law, Sophie, Duchess of Edinburgh, during their visit to the Royal Windsor Flower Show on Saturday, June 7.

In a clip shared on social media, Duchess Sophie, 60, was seen performing a deep curtsy to the monarch. With a warm smile, she dropped low in front of her brother-in-law, nearly losing her shoe in the process.

King Charles, 76, held her arms to steady her as the two then exchanged a cheek kiss.

“Beautiful moment between the Duchess of Edinburgh and the king,” one X (Twitter) user captioned the viral clip.

Fans quickly took to social media to praise the visible warmth and ease between the two royals.

“Duchess Sophie’s curtsy is perfection,” one fan wrote. “Elegant, respectful and full of heart.”

“They really do have a wonderful relationship, and her respect for him as king says so much,” another gushed.

Royal Windsor Flower Show 2025

The Royal Windsor Flower Show, held at the York Club in Windsor Great Park, marked its 118th edition at the weekend.

Charles, an avid gardener, is the show’s patron. The theme for this year’s event is Patterns in Nature, and was inspired by Charles’ 2010 book called Harmony: A New Way Of Looking At Our World.

Sophie officially opened the event, and her curtsy to the king became one of the day’s most talked-about moments.

In photos, King Charles can be seen beaming in a pale grey checked suit and burgundy brogues. Meanwhile, Sophie, in a blue floral maxi dress, maintained her poise even as her shoe nearly slipped off during her graceful kneel.

The duchess has had a busy week of engagements, including a rare double appearance with Prince William the day before the flower show.

The two visited Wadebridge in Cornwall as patrons of the Royal Agricultural Association.

William and Sophie’s close relationship was praised as they were filmed joking around. In one interaction, William jokingly scolded Sophie for sipping too much gin during a tasting session.

“You’re not allowed to finish it,” he teased, before turning to the vendor. “You’ve got to watch her.”

Sophie wore an olive green jacket with a brown suede skirt and accessorised with a green handbag and soft makeup.
