Kit Harington and Rose Leslie, who played lovers in HBO's Game of Thrones, are taking the love plunge in real life.

The two are engaged to be married.

After People broke the news Tuesday quoting a source, the BBC then featured an official engagement announcement the families published in the Times of London newspaper.

The formal post reads: “MR. K.C. HARINGTON AND MISS R.E. LESLIE. The engagement is announced between Kit, younger son of David and Deborah Harington of Worcestershire, and Rose, middle daughters of Sebastian and Candy Leslie of Aberdeenshire."

The couple played onscreen lovers Jon Snow and Ygritte on Game of Thrones starting in 2012. Leslie left the cast two years later, Harington's fan-favorite Snow has appeared in seven seasons.

Harington and Leslie confirmed their real-life romance by appearing on the red carpet of Britain's Olivier Awards in April 2016, following widespread speculation about their romantic lives dating as far back as 2012.

They shared a quick kiss while walking down that carpet together — he in his dapper tuxedo and she in her Malene Oddershede Bach gold gown.
