The pair’s epic TV romance first spilled off-screen five years ago as the couple, both 30, filmed season two of the series in Iceland.
Following a reported breakup a year later, they reconciled and made their red carpet debut as a couple at the Olivier Awards in April of last year.
In July, ET caught up with Harington at the Games of Thrones premiere, where he shared how special it was to be celebrating the show with Leslie.
“I think that's the really special thing about it -- we met on this show and here we are seven years down the line, back here promoting season seven,” Harington said. “I mean, it's mad [and] it's such a special thing. I'm so, so privileged.”
But a wife isn’t the only gift that Harrington wants to leave Games of Thrones with.
The hunk also told ET that he “hinted so heavily” about a particular set prop he would like to keep once the series wraps.
