There’s a lot going on with the British royal family these days, including new babies entering the world, Harry and Meghan’s upcoming royal wedding — not to mention Princess Eugenie’s fall nuptials — and the Queen’s 92nd birthday celebration. So it would be understandable if important anniversaries fell through the cracks.

However, this is the royal family we are talking about. They’re not only highly romantic, but apparently love to celebrate everything, including Prince William and Kate Middleton’s seventh wedding anniversary.

On Sunday, William and Kate celebrated their copper anniversary by sharing an adorable throwback photo to their wedding day, April 29, 2011.

“Seven years ago today - thank you for all the lovely messages on The Duke and Duchess of Cambridge's wedding anniversary,” Kensington Palace shared on its Instagram account alongside a photo of the couple as they drove away from their ceremony in a blue vintage Aston Martin Volante. The car, Us Weekly noted, actually belongs to Prince Charles, making the drive all the more meaningful.

Furthermore, Us Weekly explained, the car was actually decorated by William’s best man, Prince Harry, for the cute drive around London. Harry went all out for his best man duties, attaching red heart balloons and a license plate with the words “JU5T WED.”

William will soon have the opportunity to return the favor for his little brother as he will act as Harry’s best man at his wedding on May 19.

On Thursday, Kensington made the official best man announcement in a statement that read, “The Duke of Cambridge is honored to have been asked, and is very much looking forward to supporting his brother at St George’s Chapel, Windsor on May 19th.”

While making an appearance at the Greenhouse Sports Centre in London on Thursday William told reporters that being asked to be Harry’s best man, “...feels great. I’m thrilled and delighted obviously ... Revenge is sweet. I’ll be looking forward to it.”

So are we, William, so are we.
