They’ve shocked many by not being afraid to show affection for one another in public by giving each other adoring stares, holding hands and even occasionally kissing at events. However, there is a simple reason for Meghan Markle and Prince Harry’s consistent displays of public affection.

The Duke and Duchess of Sussex have been slammed in the past for using PDA just to play up the crowd and fool everyone into thinking they are happier than they really are. However, a source revealed to Express UK that isn't the case at all, and everything is genuine between the pair.

“None of it is an act,” the source said. “This is how you want the man that your best friend is with to look at her. It’s really lovely.”

However, for those who have instead been enraged not by why the couple engages in PDA, but the fact that they do at all, can be rest assured that the pair are not actually flaunting violations of royal protocol. In fact, while it may be frowned upon by some, PDA isn't actually against the rules at all.

“There’s no protocol that tells them they can’t hug or kiss or touch,” Myka Meier, who was trained by a member of the Queen’s household, told Express UK. “There’s no rule book like that.”

“Each senior member of the royal family is trusted to make the judgement calls of what’s appropriate and when,” she added. “It’s all about being trusted to make those calls on their own.”

Regardless of how the pair’s affection is received by the public, they have worked quickly when it came to their relationship. After meeting in 2016, the pair became engaged in November 2017. They were married by May 2018, and welcomed their first son together, Archie Harrison Mountbatten-Windsor, on May 6 of this year.
