Kit Harington and Rose Leslie (opens in new tab) are officially adding to their family. Yes: The "Game of Thrones" (opens in new tab) stars (opens in new tab) have welcomed their first child together.

Leslie made the news official by showing off her baby bump for the new issue of British Makeup Magazine (opens in new tab).

"Working with the beautiful Rose Leslie for the cover story of @make_magazineuk which is out now is amazing! A photoshoot by a very special team of women who captured Rose at this amazing time in her life as she prepares to become a mother for the first time!" London-based freelance fashion editor Ursula Lake wrote on Instagram along with a photo of Leslie on the magazine's shoot. "My team my team @billiescheepersphotography @liztaw did the beautiful hair and @justinejenkins did the amazing makeup. Rose wears @stellamccartney. Big thanks to @vrwpublicity for organizing the shoot and Hannah Rand for the interview."

Leslie and Harrington (opens in new tab) recently spent time at a luxurious Tudor manor house in East Anglia, which Leslie joked in an interview with Make that it was "the house Jon Snow (opens in new tab) built."

It's a fitting joke for the pair, who met on the set of HBO's hit fantasy epic "Game of Thrones" (opens in new tab) and played star-crossed lovers Jon Snow and Ygritte.

The actors fell for each other off camera as well, and were first reportedly in an actual relationship in 2012. They briefly broke up, but got back together and eventually (finally) confirmed their real-life love connection in April 2016; by September 2017, Leslie and Harrington announced their engagement (with an old-fashioned newspaper ad in The Times). They tied the knot in June 2019 in a lavish ceremony at a Scottish castle, in typical "Game of Thrones" fashion (opens in new tab).
