But then Craig speculated that girls are more difficult than boys as teenagers.

"That's not my problem, that's daddy's problem," Mila said, in reference to her fiancé Ashton.

The pair got engaged this February, after two years of dating.

Also on the show, Mila confirmed that she was breastfeeding and credited it with helping her to lose weight.

During her pregnancy, Mila talked about how Ashton had helped her with her cravings.

"I'm very stereotypical. I eat sauerkraut all day long," she said. "This is the worst craving to have because it smells so bad. He preempted this, and assumed I'd have goofy cravings. So he stocked our secondary fridge with stuff like pickles and sauerkraut, just in case during this pregnancy I'd say 'I really want something..."

The actress had never been keen on the idea of marriage but she said falling for Ashton, 36, changed her mind.

"I never wanted to get married. From the age of 12, I prepared my parents for no marriage. Then things changed—I found the love of my life," she said. "We all get movie star crushes... I’m marrying mine."
