One month after their relationship was made public, 30-year-old Harington, opened up about the early days of their romance.
A source confirmed the happy news to PEOPLE magazine.
The pair first caught the attention of viewers, while stirring up relationship rumours in 2012 at the same time as their fictional "Game of Thrones" characters, Jon Snow and Ygritte.
Although reports revealed that the pair split a year into their relationship, they later got back together and picked up from where they left off, fueling romance speculation until they officially confirmed their relationship in April of 2016.
They made their red carpet debut as a couple at the Olivier Awards in London.
One month after their relationship was made public, 30-year-old Harington, opened up about the early days of their romance, which we now know began on set while shooting in Iceland for season 2.
He admitted that those weeks were his favourite in the series.
“Because the country is beautiful, because the Northern Lights are magical, and because it was there that I fell in love,” he said in a cover story for L’Uomo Vogue. “If you’re already attracted to someone, and then they play your love interest in the show, it becomes very easy to fall in love.”
We are super excited for them and wish them the best of luck!
