Mila Kunis often forgoes the celebrity party line in favour of the unvarnished truth – and one thing she isn’t afraid to speak openly about is motherhood.

The actress has two young children (daughter Wyatt and son Dmitri) with partner and former That 70s Show co-star Ashton Kutcher, and has previously said that “children are f***ing crazy”.

She has also defended her right to breastfeed in public, and observed that it’s in both her and her kids’ interests for her to be a “happy, fulfilled woman” with a successful career (here, here).

And now, in a new interview with Ellen DeGeneres, Kunis has opened up about the realities of parenting a boy and a girl – hilariously nailing the big difference between the genders in the process.

“My boy’s like a sloth,” she explained bluntly during her appearance on The Ellen Show. “He’s wonderful, and I love him – ’cause one day he’ll probably watch this and be like, ‘Why did you say that?’ – but the truth is, women are smarter than men. And I have this evidence from my two different humans that I created.”

Kunis continued: “Girls are just on it and boys are like, ‘Dum da-dum da-dum da-dum,’ they’re more like little linebackers going through life, and like … Neanderthal-ish. Wyatt will be like ‘Pass the cup, please,’ and my boy’s like ‘ungh, ungh.’

“That’s it! That’s all you get and you’re like, ‘Ungh? What could ungh be?’ You look around, you’re like, ‘Ah, ball!’ There’s just a huge difference.”

Mila Kunis says this is the difference between raising a son and a daughter
