I don't know much about the GOT duo. But like it said below, 4yrs to reveal. And wasn't one of them off the show when they finally did come out?
Kit Harington and Rose Leslie dated off and on beginning in 2012, she left the show in 2014, they went public in April 2016 and the latest gossip now that everybody and their blind-ass grandma
have been allowed in can see they’re a thing is that they’re “finally” moving in together (via Refinery29). In 2013, Kit called Rose a “very good friend” and they both have been cagey and not always on the same public narrative page when it comes to the nature of their relationship, so a ton of mixed messages and interviews that don’t add up have been part of the are they/aren’t they gossip.
So on again/off again, not following the general Hollywood ish of moving in together before the wet spot on the sheet dries, misleading the public and the media during interviews, and spending years navigating their new celebrity as it pertains to their relationship before becoming more open? I’ve said it before and I’ll say it again: THIS. SHIT. HAPPENS. ALL. THE. TIME.
