Mila Kunis was a guest star on James Corden's debut Late Late Show on CBS on Monday, March 23 — and the cheeky British show host made the new mom admit baby Wyatt was on her mind at all times, even when she's having sex!

Kunis, who gave birth to her first baby five-and-a-half months ago, was talking parenthood with Corden, who welcomed his second child in October, revealing she and Kutcher made sure to go on a date night once a week, where they attempted not to talk about their daughter.

"Somebody gave us that advice when I first got pregnant, to make sure we have time for ourselves," Kunis explained. "My parents live down the street, so we have them do what's called monitor sitting, so the baby goes down to sleep and they have to watch the monitor. So I would say once a week we go on a date or something, just to connect. And we make an effort not to talk about the baby."

When fellow guest Tom Hanks asked Kunis if that was even possible, she admitted it was tough. "It's hard," she said, "But for that one hour we try very hard to connect."

Cheeky Corden cut in, insisting thinking about anything other than your newborn was impossible when you're a parent — even when you're having sex.

"It's almost impossible when you've had a child," the new show host insisted. "To the point that you may be talking about it when you're having sex," he continued.

Collapsing into laughter Kunis insisted she'd never actually spoken about Wyatt during a moment of passion, although she admitted her mind did wander now and again! “I've thought it but I've never said it," she revealed, giggling even more. "I have been like, 'I wonder if that's her, making that noise....wait, what's happening?'"
