Prince William has stepped out in honor of his late mother, Princess Diana's 65th birthday.
The royal was accompanied by his father, King Charles, and stepmother Queen Consort Camilla. The trio was seen making their way to attend the Order of the Thistle service that was held at St. Giles' Cathedral in Edinburgh, Scotland.
This historic event reportedly coincided with his mother's birthday, who passed away in a tragic car crash in France in the year 1997. Known as the Duke of Rothesay, the 44-year-old prince was seen wearing the traditional deep green velvet robes with a black hat that was adorned with white ostrich feathers.
He arrived along with his uncle, Prince Edward, who joined King Charles III and Queen Camilla for his highly honorable ceremony.
