The former 'Game of Thrones' co-stars - who married in June 2018 - are "delighted" after the 36-year-old actress recently gave birth to a baby girl, a sibling for their two-year-old son.

As with their little boy, the couple haven't made their daughter's name, or other details surrounding her birth, public.

Kit's spokesperson simply told “They’re delighted to have welcomed a little girl into the family."

The 'Eternals' actor admitted in March he and Rose had been more "practical" with her second pregnancy, whereas they took a more "romantic" view of parenthood when they were expecting their son.

He told 'Entertainment Tonight': "We're really practical about it at the moment. And actually, almost too practical.

"With our first child there was so, sort of romantic, for one of a better word, and this other one we're like, 'Right, okay, let's get.' We know how efficient we have to be. Let's get down to parenting.

"My mum says that she never remembers us being little kids or the early parenting much, because you're so present in it. And I think that's what kids allow you to be, is incredibly present in the moment, 'cause you've got no choice."

The 'Extrapolations' actor joked his son is going to get the "shock of his life" when there's a new baby in the house but he thinks the tot will eventually make a "great older brother".

He said: "I don't know if he's really conceptually understood anything yet. He's about to get the shock of his life.

"He's just loving life. My boy loves life. He charges around, and I think he's going to be a great older brother. It's just really exciting."
