Prince William and Kate Middleton Celebrate 13 Years Together With a Previously Unseen Photo From Their Wedding—See the Portrait Here

Prince William and Princess Catherine are celebrating 13 years of marriage together with a never-before-seen photo from their wedding.

The regal black-and-white photo was shared to the Princess and Princess of Wales' social media channels today with the caption: "13 years ago today!" The portrait shows the royal couple standing happily together while sporting their wedding-day looks.

Prince William and Princess Kate tied the knot in 2011 at Westminster Abbey in London, England. For their nuptials, the Princess of Wales donned a classic Sarah Burton for Alexander McQueen wedding gown. The style featured an ivory lace bodice with long sleeves and a satin skirt. Prince William wore the red runic of the Irish Guards, but changed into the black uniform of the Blues and Royals—which he is wearing in this photo—following the ceremony.

Photographer Millie Pilkington, who is credited for the never-before-seen photo, also shared it to her socials. "Wishing the @princeandprincessofwales the very happiest wedding anniversary. Can’t believe it is 13 years ago almost to the hour, that I took this portrait. So excited and honoured that they should wish to share it," she wrote in an Instagram post.

Westminster Abbey also commemorated the Princes and Princess of Wales' anniversary by sharing a video of the royal couple on social media. The post was captioned: "Wishing The Prince and Princess of Wales a very happy wedding anniversary today! Their Royal Highnesses were married here in the Abbey #onthisday in 2011." The video features Prince William and Princess Kate leaving the Westminster Abbey following their ceremony 13 years ago.
