Their wedding day was watched by royal fans all around the world, and today is the pair’s seventh anniversary as husband and wife.
To mark the occasion, the Kensington Palace official Twitter account posted a particularly candid photo of the pair from their wedding day.
Rather than a glamorous photo of the couple at the altar or in the royal carriage, the Palace chose a very different picture altogether.
The image shows the two driving an Aston Martin as they leave the wedding reception together.
The blue vintage Aston Martin, which had a ‘JUST WED’ license plate and a learner sign, is owned by William’s father Prince Charles, 69.
The car was adorned with corsages, ribbons and balloons. It brought a more casual note to the royal wedding celebrations.
The Kensington Palace tweet was captioned: “Seven years ago today.
“Thank you for all the lovely messages on The Duke and Duchess of Cambridge’s wedding anniversary!”
Royal fans rushed in to share their own personal memories of Kate and William’s special day.
One wrote: “Happy 7th Anniversary to Their Royal Highnesses The Duke and Duchess of Cambridge!! It felt like yesterday I was watching your beautiful wedding.”
Another wrote: “Happy 7th anniversary to Their Royal Highnesses The Duke and Duchess of Cambridge.
“I was eleven years old when the wedding took place and completely awestruck and utterly intrigued.
“They continue to inspire me every day. May God bless.”
Kate and Prince William’s royal love story spans over 16 years, since they were students together at St. Andrews.
The future couple met when they studied the undergraduate degree: Art History.
They shared a house together at university along with two other friends in 2002.
It later became apparent the pair were in a romantic relationship after they were pictured skiing together in Klosters, Switzerland.
They broke up shortly in 2007 while Prince William served in the armed forces.
However, they reconciled later that year, and announced their engagement in 2010.
