Kit Harington has revealed to being worried about the arrival of his second child with former Game of Thrones co-star Rose Leslie.
The couple, who met on the hit HBO show Game of Thrones as lovers Jon Snow and Ygritte, wedded in 2018 at her ancestral home in Aberdeenshire.
Their son, whose name has not been made public, was born in 2021.
Kit, 36, announced the happy news on The Tonight Show with Jimmy Fallon on Friday.
Kit coyly announced that their now two-year-old son will soon have a sibling after the talkshow host stopped in and asked about him.
‘He is about to get the shock of his life, which is that he’s about to get a brother or sister,’ he said.

As the audience started roaring and clapping, Jimmy, 48, was taken off surprise and said ‘are you serious?’.
Kit nodded and verified he was expecting another kid before Jimmy congratulated him and they shook hands.
However, the actor afterwards expressed his fear.
‘You know how you’re like, walking on clouds and dancing through meadows of daisies for nine months with your first baby?’
‘Well the man is anyway,’ he added.
‘This time the reality check comes much shorter and you get practical, like, real quick.’
Although Kit and Rose told their son that there will be a new baby soon, he ‘doesn’t fully cognitively get it just yet,’ he added.
‘We are trying to get him ready for it and we point at Rose’s belly and we say “Mummy’s baby, mummy’s baby” and he points at his tummy and goes, “My baby, my baby.”‘
But as he said, he’ll figure it out ‘soon enough’.

Kit made the choice to disclose the news on television after speaking last month about his reasons for avoiding social media.
He said it all started when he was reading Game of Thrones reviews and comments, which he said’screwed with me’ and ‘hurt’ his confidence for a long time.
‘I think each to your own and some people probably find a lot of brilliant stuff in social media, but I think for an actor in a show like this, it’s the most dangerous thing,’ he said.
He added: ‘So…
I’m not on social media, I had to step away from that stuff.’
The Tonight Show Starring Jimmy Fallon airs on NBC in the US.
