Indeed, news of the pregnancy won't come as a surprise to fans – both Mila and Ashton have been vocal about their love of parenthood. "You think you know how much you love another person, and then you have a child and you realise you didn’t know," Ashton, 38, previously told Ellen DeGeneres. "I think I really look at this as the greatest opportunity of my life."

He continued: "But the most amazing thing about having a baby is my partner, Mila. She's the greatest mum – I can't even! Like, I go to work every day and I come home and she's perfect."

Mila, 32, has also spoken about the positive impact becoming a parent has had on her. "Everything is different, from the fact that you're so happy when you get six hours of sleep, to the idea of being responsible for this incredible, living, breathing little human being that you can't believe is yours," she told Business Insider last October.

When asked if she hoped to have more children in the future, the Bad Moms actress replied: "Not today, but yeah, absolutely. For sure!"

Congratulations to Mila and Ashton on their exciting news!
