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 the sweet snap with Prince George, 12, Princess Charlotte, 10, and Prince Louis, 8.

In the outdoor shot, William, 43, relaxed in 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 years after their engagement.

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

Their friendship took a romantic turn two years later.
