Mila Kunis thinks her daughter is "smarter" than her son.
The 'Spy Who Dumped Me' actress has Wyatt, three, and Dimitri, 15 months, with her husband Ashton Kutcher and she's amazed at how "incredibly different" they are from one another.
She said: "They're incredibly different. My boy's like a sloth. 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 evident from my two different humans that I created.
"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."
And the 34-year-old star joked Dimitri's communication is very basic.
She quipped: "[I'll] be like, 'Pass the cup, please,' and my boy's like [pointing and going] '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 admitted her youngest child prefers to run rather than walk, but he's still quite "lazy".
When talk show host Ellen pointed out Dimitri is always being carried in a "contraption" on Ashton's back, her guest said: "He doesn't walk -- he just runs. He's in the hiker backpack a lot when we hike, but that's 'cause we're hiking and he's a year old, guys! He's lazy."
Meanwhile, the 'Bad Moms' actress recently revealed Wyatt loves to wake up on Fridays because she knows she is allowed to consume some wine as part of Shabbat, Judaism's day of rest.
The 'Friends with Benefits' star said: "We do Shabbat at our house. At Shabbat, you have a sip of wine. My daughter had a sip of wine since she was born ... Friday mornings she wakes up and I say, 'It's Friday,' and she says, 'I can have wine!'"
