Perhaps it should have come as no surprise that Game of Thrones sparked some real-life romances. After all, the cast often filmed in remote locations for months on end, so there was plenty of time to get to know one another intimately. The series also went on for an impressive eight-season run (though it ended disappointingly early for many fans). 

Since the show included so many established actors, however, it should also perhaps come as no surprise that some of the people coming to the set had romances before being cast together on the show. That was the case for Lena Headey and Jerome Flynn, who dated long before the series began.
