Prince Charles and Camilla, Duchess of Cornwall, celebrated their 15th wedding anniversary Thursday, weeks after it was revealed the 71-year-old royal tested positive for coronavirus.

In a photo posted Wednesday from Clarence House, the couple’s official Instagram account, the pair posed together from their Scottish Birkhall estate with their pets.

“Ahead of The Prince of Wales and The Duchess of Cornwall’s 15th wedding anniversary tomorrow, we are sharing this photo of Their Royal Highnesses with The Duchess’s dogs Bluebell and Beth,” Clarence House captioned the image, noting the photograph was taken earlier Wednesday.

Charles and Camilla, 72, married in a civil ceremony at Windsor Castle on April 9, 2005. He divorced the late Princess Diana in 1996, and she split from husband Andrew Parker Bowles — who recently announced he tested positive for coronavirus — in 1995.

In late March, Clarence House confirmed Charles tested positive for coronavirus. The heir to the British throne had experienced “mild symptoms” and was self-isolating at his Burnham home in Scotland. Charles was out of self-isolation a week later, per reports.

On April 1, Charles made his first public appearance since his initial diagnosis.

Camilla, who tested negative for the novel virus, is said to have ended her self-isolation period on Monday and reunited with Charles, according to People.
