Prince Harry’s girlfriend Meghan Markle will attend Pippa Middleton’s wedding

The couple will definitely draw attention at Pippa Middleton’s nuptials but their presence will be discreet.

Kate Middleton’s younger sister is set to say “I do” to her partner, businessman James Matthews, on May 20, at St Mark’s Little Church in Englefield.

The event may also be an opportunity for Prince Harry and Meghan Markle to formalize their relationship by making an official appearance as a couple.

According to People magazine, the Suits actress will be able to attend the reception, but not the ceremony.

Myka Meier, founder and director of Beaumont Etiquette, explained to the publication that unmarried couples shouldn’t attend religious wedding ceremonies.

In addition, the invitations were launched last fall, when the relationship between Prince Harry and Meghan Markle was in its infancy.

“I would not be surprised if Prince Harry was not given a plus one, as the wedding guest list would have most likely been made in fall of last year when Prince Harry’s relationship with Meghan was not as public,” Meier said. “I typically recommend if someone is married, engaged, considers themselves to have a serious significant other, or is traveling in for the wedding, they should receive a plus one. Pending how intimate Pippa wants to keep her wedding, she may very well follow the ‘no ring, no bring’ rule.”
