Kensington Palace released the images of the loved-up couple just after they announced their engagement in November 2017, when royal watchers examined every detail of the stunning shots.
And now the photographer behind the lens, Alexi Lubomirski, has finally revealed how he came to shoot one of the world's most recognisable couples ahead of their big day.
"It was nutty. It was a very surreal end to the year because it came out of nowhere," the photographer told E! News.
Alexi, who had never been hired to take 'engagement' photos before, revealed that the couple found him in a thoroughly modern way: through a friend on Instagram.
"I think one of Meghan's friends saw me on Instagram that I was in England during the announcement of the engagement and I was told later that this person said to her, "You should meet Alexi. He's great. You'd love him", and that was it.,"
The photographer, who is known for shooting A-listers such as Angelina Jolie and Beyonce, said all he asked of the couple was to 'be themselves' while he took photos, and added that capturing the pair looking utterly besotted with each other was easy as they "were so deliciously in love."
For his part, Alexi - who is a prince of the Polish House of Lumbomirski - has been invited along with his wife to the big day in May, however it won't be as the official wedding photographer.
Prince Harry and Meghan Markle will tie the knot on May 19th on front of 600 invited guests.
Plans are in place for a 'fun' wedding day where things will be a little more informal than royal weddings before it.
The couple have invited 2,640 people in total – including 1,200 members of the public “from every corner of the United Kingdom” – into the grounds of Windsor Castle.
"This wedding, like all weddings, will be a moment of fun and joy that will reflect the characters and values of the bride and groom," an official statement from Kensington Palace said.
"Other guests will include 100 pupils from two local schools, 610 Windsor Castle community members and 530 Members of The Royal Household and The Crown Estate." Kensington Palace said in an official statement.
The couple has requested charity donations in lieu of wedding gifts.
