We're taking a look back at some of our favourite royal kisses of all time, and who better to start with than Prince Harry and Meghan Markle? The royal couple of the moment, who married in May 2018, haven't been shy in showing their affection for one another.
The Duke and Duchess shared a sweet public display of affection as they attended the Sentebale Polo Cup together in July 2018. Prince Harry couldn't resist puckering up for a kiss on the lips with his wife Meghan as he celebrated his team's victory at the Royal County of Berkshire Polo Club.
The Duke and Duchess of Sussexshared their first public kiss shortly after their church ceremony, with Meghan tentatively asking Harry "Do we kiss?" The groom replied "Yes," before leaning in to kiss his new wife. The couple delighted fans with a second kiss during their carriage procession, as they rode around the streets of Windsor, greeting crowds.
Harry and Meghan are very tactile for a royal couple. They've often broken with royal protocol and indulge in public displays of affection, openly holding hands and embracing each other at public outings – such as at their first official joint engagement in Nottingham, a few days after they announced their big news.
