Prince William and Kate Middleton ring in 15 years of marriage with precious family photo

Prince William and Kate Middleton marked their 15th wedding anniversary on Wednesday with a new family photo.

“Celebrating 15 years of marriage ❤️,” the Prince and Princess of Wales wrote via Instagram alongside a sweet snap with their children: Prince George, 12, Princess Charlotte, 10, and Prince Louis, 8.

In the outdoor shot, William, 43, relaxed on the grass in a polo and shorts, two dogs on one side of him and his eldest child on the other.

Middleton, 44, lounged between George and Louis, holding hands with the little one.

Charlotte was all smiles at the end of the group.

William and his wife walked down the aisle at Westminster Abbey in April 2011, six months after their engagement.

The pair met in September 2001 while attending St. Andrews University in Scotland.

Their friendship took a romantic turn in 2003.

Last year, William spoke about not repeating the same “mistakes” in his marriage that his dad, King Charles III, and late mom, Princess Diana, made during their union.

The duo wed in 1981 and separated in 1992, officially divorcing one year before Diana’s tragic 1997 death.

“You take that [example] and you learn from it,” the future king told Eugene Levy during an October 2025 “Reluctant Traveler” episode. “I think we all try and do that.”

William noted his home environment as a child was “warm” for only “a short period of time.”

“I think it’s really important that that atmosphere is created at home,” he added. “You have to have that … feeling of safety, security, love.

“I just want to do what’s best for my children, but I know that the drama and the stress when you’re small really affects you when you’re older,” William continued.

He and Middleton became parents in July 2013 when George arrived, followed by Charlotte and Louis in May 2015 and April 2018, respectively.
