The 34-year-old beauty - who has daughter Carmen, four, and sons Rafael, two, and 18-month-old Leonardo - announced in November that she was expecting her fourth child with Alec Baldwin, and Hilaria is feeling calm about giving birth, having been through the experience three times previously.

She shared: "With a fourth pregnancy, you see the light at the end of the tunnel earlier. There's calmness and comfort from experience."

Hilaria also revealed she feels overcome with a feeling of nostalgia before giving birth.

Speaking to Parents magazine, she explained: "I recently posted about a moment of semi-sadness I had that Leo won't be my youngest anymore.

"I feel that way each time Alec and I have a new baby!"

This comes shortly after Hilaria described her husband as an "old school" parent.

The fitness and wellness expert admitted her husband often leaves her to "take care of the kids".

She said: "I'm the kind of person where I could get so wrapped up in my kids and I could lose my relationship a little bit and just assume, 'Don't you love doing this too? Isn't this so much fun?'

"[Alec]'s a little bit more old school. 'You're the mom, you take care of the kids, and then I will come and go and I will read a book with them every once in a while' kind of thing."

Despite the stresses of parenting, Hilaria and Alec still find time to enjoy date nights together.

She said: "Most nights, we have date night, which could mean we're doing a puzzle. On Valentine's Day, we ordered takeout.

"My husband had just gotten his hip replaced. We walked, on one of his first [post-surgery] walks, to go get food, and we ate it out of the plastic. And then we looked at each other like, 'Can we go to bed now?'"
