Kate Middleton, Prince William Share Intimate Photo on 14th Anniversary

Kate Middleton and Prince William may have spent their 14th wedding anniversary on royal duty, but they were able to steal a quiet moment with each other.

The royal couple capped off the first day of their trip to Scotland on April 29 by sharing an intimate photo taken during their day on the Isle of Mull on social media. The snap showed William, 42, and Kate, 43, from a distance turned away from the camera, wrapping their arms around each other’s backs as they took in the beautiful landscape.

They captioned the image, “Wonderful to be back on the Isle of Mull. Thank you to everyone for such a warm welcome.”

They signed off with a red heart emoji and their initials, “W & C,” standing for William and Catherine. This practice indicates that the message came directly from the pair rather than their team.

The Duke and Duchess of Rothesay, as the couple is called in Scotland, were full of flirty moments throughout their day, sneaking in looks of love and small displays of affection. Kate — who has been spotted tapping her husband on the backside occasionally! — leaned in close to her husband as they walked through the town, smiling as her hand grazed his back.

In another sweet moment, Kate rested her head on Prince William’s shoulder and placed her hand on his back in a photo taken from behind.

After Kate’s cancer diagnosis last year, royal biographer Ingrid Seward told PEOPLE that the couple were less inclined to hide their displays of affection from the public eye.

“They are happy for people to see them be touchy-feely,” she said. “They’re in a different phase of their life now. William is very protective and very proud of her for coming through this and carrying on with her life.”

Prince William and Princess Kate’s first stop was in the town of Tobermory on the Isle of Mull, where they visited a community hub and an artisan market. Later in the day, they checked out a local croft to learn about sustainable farming and hospitality on the island.
