Jamie Dornan says the number of children he has is ''up to'' his wife.

The 36-year-old actor is already father to Dulcie, four, and Elva, two, and whilst his wife Amelia is currently expecting the pair's third child, he says there could be more tots on the way if his spouse is ''willing''.

He said: ''Part of me feels like [I need] to put a cork in it after this. But then, alternatively, I feel like we make really great kids. Maybe we'll just - if my wife's willing - do it until we can't do it anymore.

''It's all up to her. I do the fun bit.''

Jamie plans to make room in his schedule to be at home more often when his third child arrives, as with both of his daughters, he was ''at the mercy'' of his role as Christian Grey in the 'Fifty Shades of Grey' franchise.

Speaking during an appearance on 'Jimmy Kimmel Live!' on Monday (22.10.18), the 'A Private War' star said: ''I think for this one, I'm going to have a lot more control over [my schedule]. [With] the first two [kids], I was sort of at the mercy of 'Fifty Shades' schedule.

''The first one we had in Canada, and I started filming three days after she was born. The second one we had in London, and I flew to Canada 10 days later and started filming the second. But this time, I'm trying to take proper time off for a few months after, as well.

''I've never missed a birth - I couldn't live with myself if I missed the birth.''

His comments come after he recently revealed he has never signed up to social media, because he thinks it distracts people from spending quality time with family.

Asked about his decision not to have a presence on such apps, he said: ''Yeah, definitely. Especially now with two kids and another on the way. I'm not on social media or anything. I guess that takes up a lot of people's phone screen time.

''I think especially if you've got kids and they want to play with you and you're watching what people had for breakfast then that would seem really bad. But, you know, I think the less time we spend on our phones and the more time we are together with other human beings, it's a good thing. But, sadly, I think it's going the other way.''
