The actors first stirred up relationship rumors in 2012, in sync with their fictional "Game of Thrones" counterparts, . Though they reportedly split after a year, they later reconciled and continued to fuel romance speculation until they officially confirmed the relationship in April 2016, making their red carpet debut as a couple at the Olivier Awards in here.
