Hilaria Baldwin has claimed her romance with husband Alec Baldwin is "no fairy tale"

Posting a professional shot of the pair at a red carpet event, she wrote: "I met him 7 years ago today...and how our lives have changed. 5.5 years of marriage, almost 4 kids...we have had a wonderful time and our moments too. One thing that helps us grow together is that we make it a priority to have our alone time. Children are such a blessing, but they can strain relationships too...taking time, nearly every day, to check in and laugh...yes, get angry and cry and frustrated too-helps us stay together. It is no fairy tale and it isn't easy...but it's real and it's us. Most importantly: never to lose our sense of humor. (sic)"

Hilaria - who already has Carmen, four, Rafael, two, and 17-month-old Leonardo with Alec - rounded off her post by joking that the key to their lasting marriage was the 59-year-old actor's ability to know when his wife is right.

She concluded: "By the way, Alec just interjected: "I realize, at the end of the day, Hilaria is usually right." Me: that helps too: honesty . What are your tricks to sticking to sticking together? #WeGotThis2018 (sic)"

Alec - who also has 22-year-old daughter Ireland from his previous relationship with Kim Basinger - and Hilaria will welcome a baby boy in the coming months, and the brunette beauty previously revealed she "really likes" being a mother.

She said: "I never knew how many kids I wanted to have. I didn't know how much I'd like it. And I really, really like it ...We were like, 'Oh, should we have another kid?' We were like, 'You know what? Let's try something different - let's try.' [With] the other ones, it's not like we were like, 'Oh my God, how did this happen?' But this is the only one we [planned]."
