While there’s no official rule against Prince William and Kate Middleton sharing public displays of affection, it isn’t often in their nine years of marriage that we’ve see these two royals sharing a kiss in public — or even holding hands.

“The likely reasoning is more that while traveling on a tour, such as the India trip, technically the couple are working representatives of British Monarchy,” royal etiquette expert Myka Meier told People. “The couple are likely to show very little PDA, if any, to remain professional during their designated roles abroad.”

“Going to somewhere like the mausoleum is very much an official, straight-laced kind of event and you wouldn’t hold hands there if they’re there on an official visit,” royals writer Judy Wade told People. “Different types of occasions call for different types of behavior.”

Private moments, while rare, are not entirely impossible to find. We’ve rounded up all of the times the royal couple couldn’t help but steal a smooch or a sweet embrace on the world’s stage.

Most recently, the Cambridges offered a subtle gesture during a trip to Wales to discuss how the tourism industry was handling the COVID-19 pandemic. William showed off his skills at an arcade claw game and Kate was right there with him. Whether she was offering a show of support with her hand on his back or urging him to pick the cutest plush is a secret only they'll know.

Of course, if the couple is celebrating a family milestone, like the debut of a new royal baby, a little affection is expected.

And even though every public appearance is technically a professional event for the two, that doesn't mean that the Cambridges can't hold hands.

And a little black tie PDA is never a bad thing, even if it's just William's hand on Kate's back.
