Premiere Of HBO's 'Game Of Thrones' Season 7 - ArrivalsAfter sparking marriage rumors this summer, former "Game of Thrones" costars Kit Harington and Rose Leslie have now reportedly made things official: Sources tell People that the couple is indeed engaged.

According to People (which, for what it's worth, is the most reliable celebrity gossip outlet on the market), a source "confirmed" the news, though neither Harington (who plays Jon Snow on the HBO series) nor Leslie (who played Ygritte) has publicly commented on the report yet. The pair -- who played love interests on "Thrones," and shared a steamy season three sex scene -- started dating in real life in 2012, briefly broke up, and then reconciled, before making their public debut as a couple in April 2016.

Back in July, a tabloid report claimed that Harington had popped the question, though a rep for the actor later debunked that rumor. In June, Harington briefly touched upon his future with Leslie in an interview on "The Late Late Show With James Corden" -- egged on by none other than Nicole Kidman -- and said that the actress had recently moved into his house.

Congrats to the soon-to-be-newlyweds!
