Alec and Hilaria Baldwin are enjoying every bit of their “alone time” before their fourth baby is born

Posting a picture of the pair on Instagram, 34-year-old wellness expert Hilaria said: “Alone time before number 4 comes...Alec always tells me that no matter how many kids we have and that we are “husband” and “wife”, I’ll always be his girlfriend. We really work hard to maintain this. How do you feel about this in your own relationships? #WeGotThis2018 is @apeainthepodmaternity (sic)”

It comes after Hilaria - who married the 60-year-old actor in 2012 - recently said she could “see the light at the end of the tunnel” with her fourth pregnancy, as she knows what to expect.

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

Hilaria also previously explained how her ‘Boss Baby’ husband is “old school” when it comes to his views on parenting.

She revealed: "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.”

And 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?'"
