Game of Thrones’ Kit Harington and Rose Leslie are expecting their second baby

You know something, Jon Snow. You know a baby is on the way!

Game Of Thrones‘ Kit Harington announced that he and his wife Rose Leslie join their pack, which will be quite a surprise for their 2-year-old son.

“He’s about to get the shock of his life,” Kit shared during a Feb. 3 appearance on The Tonight Show Starring Jimmy Fallon“which is that he is about to have a sibling.”

Kit shared that he and Rose, who played his character Jon Snow’s love interest Ygritte, on Game Of Thrones, worked on explaining her pregnancy to their son before becoming a big brother. But it didn’t turn out to be easy.

“I’m not sure he’s got it conceptually yet,” the actor said. “We’re trying to get him ready. We point to Rose’s belly and say, ‘Mama’s baby,’ and he points to her belly and says, ‘My baby.'”
