A lot has changed since the couple tied the knot in 2011.

The Duke and Duchess of Cambridge mark their tenth wedding anniversary today. In light of the occasion, the couple shared two never-before-seen portraits by photographer Chris Floyd. The new photos were taken at Kensington Palace. In one of the pictures, Prince William and Kate Middleton are wearing blue tones, which is a nod to the outfits they wore when they announced their engagement back in 2010. In a statement on behalf of the royal family, Queen Elizabeth sent her congratulations to the Duke and Duchess as they celebrate ten years of marriage. The message reads: "Wishing The Duke and Duchess of Cambridge a very happy wedding anniversary. Today marks ten years since Their Royal Highnesses exchanged vows at Westminster Abbey." https://twitter.com/RoyalFamily/status/1387665126644457473 It may be hard to believe, but William and Kate did in fact tie the knot on this day in 2011. Their royal wedding at Westminster Abbey was watched by millions, both in the United Kingdom and around the world. A lot has changed for the royal family since their April wedding. Most notably, the couple have welcomed three children - Prince George, Princess Charlotte and Prince Louis. The couple celebrated Prince Louis's third birthday last week by sharing new photos taken by Kate Middleton herself. The baby of the family followed in his older siblings footsteps as he started attending the Willcocks Nursery School in Kensington. https://twitter.com/KensingtonRoyal/status/1387519624883982336 The past year has been an eventful one for the royal family, to say the least. Earlier this month, William and Kate joined members of the royal family at the funeral for Prince Phillip, the Duke of Edinburgh. The Queen's late husband passed away peacefully in his sleep on April 9. Prior to that, the royal family were headline news for weeks following Prince Harry and Meghan Markle's tell-all interview with Oprah Winfrey. Prince William responded to allegations of racism made against a member of the family by saying that they are "very much not a racist family".
