Meeting on Game of Thrones.
The couple met on set while filming season two of Game of Thrones back in 2011. Leslie played Ygritte who falls in love with Harington’s character Jon Snow.
Five years later in an interview with Vogue Italia, Harington recalled the moment he fell in love with Leslie while filming the show in Iceland.
"The country is beautiful, because the Northern Lights are magical, and because it was there that I fell in love," he told the publication.
"If you're already attracted to someone, and then they play your love interest in the show, it's becomes very easy to fall in love."
