While there were rumors that Meghan Markle was not formally invited to Pippa Middleton’s summer wedding last year–one thing was certain: she and then boyfriend Prince Harry did attend the reception as a couple.

When Pippa Middleton married former race car drive and hedge fund manager James Matthews in May of 2017, Harry and Meghan were newly dating and had just recently been outed as a pair. The media attention was enormous. Respectfully, the twosome chose to stay out of the spotlight on Pippa’s big day and only make an appearance at the after party. In fact, Prince Harry drove an hour and half back to London to retrieve Meghan to attend the post nuptial bash and then another hour and a half back to the Middleton estate with his girlfriend. Swoon.

Still, it was Pippa who inadvertently stole the spotlight from older sister Kate Middleton on her wedding day when she wore the now iconic figure flattering white bridesmaid dress. The fitted and low cut draped style called attention to all her ahem, best assets. Bum-gate caused a media frenzy but Pippa Middleton had a sense of humor about all the hoopla saying, “As I found out, recognition has its upside, its downside and -you may say- its backside.”

So, will Pippa Middleton and James Matthews be attending the royal wedding?

While there has been a great deal of speculation about the May 19th wedding of Prince Harry and Meghan Markle and the guest list–one thing is certain: the pair have chosen to invite only people with whom they have a close or personal connection. While Kate Middleton and Prince William’s wedding was a large and lavish affair with 1900 guests, Harry and Meghan have opted for only 600.

While it would be extremely unlikely that any of the Middleton family would be left off the guest list–their attendance is still up in the air. It’s doubtful that Pippa and Meghan have had much time to get to know one another or spent significant time together and Prince Harry has never been spotted socializing with James Matthews.

The Middleton family will likely attend as a way of supporting Kate and her husband’s brother as well as showing support for the Queen’s grandson.
