Mila Kunis thinks about her daughter all the time

Speaking on his presenting debut on the talk show, James - who has his two kids with wife Julia - told Mila: "It's almost impossible once you have a child, to the point where you might even be talking about it during sex. 'You know, she almost rolled over today.' 'Really? That's amazing.' "

The 31-year-old star chuckled and replied: "That's never happened! I've thought it, but that's never happened!"

James then quipped: "Then you look and it's him and he's just crying during sex. That's what he does."

Mila also admitted she definitely wants more children and while she and Ashton talk about Wyatt all the time and spend most of their time looking after her when they are not working, the couple try to treat themselves to a date night every week.

She added: "Somebody gave us that advice when I first got pregnant, to make sure you take the time for yourselves.

"My parents - we're very lucky - live down the street, so we have them do what's called 'monitor sitting. "The baby goes down to sleep and they have to watch the monitor. I would say once a week we go out on a date. It's not just the two of us, but like a double date or something.

"But yeah, [it's] just to reconnect, and we make an effort to not talk about the baby."
