From the outside looking in, actress Nicole Kidman seems perfectly happy in her marriage with country star Keith Urban.
But the Aquaman star opened up about a major regret in a new interview: her family with the musician just isn't big enough.
Kidman and Urban have two daughters together: 11-year-old Sunday rose and 9-year-old Faith Margaret. Kidman also has a pair of grown-up adopted children with her ex-husband Tom Cruise, but her relationship with them has been famously testy.
Kidman, 51, told People she would have liked to have even more kids with Urban, also 51, but says their ages have ruled out any more children.
The Australian actress said she's "so grateful," for her daughters, but would have filled her house with children if she met Urban in her younger days.
"We go, 'Oh gosh, I wonder if we met when we were 25, then we could have had 10 of them!'" she admitted.
"But Keith says, 'Stop the wanting mind.' It's far better to be completely in love and satiated with what you've been given, what we've been given."
Kidman also opened up to People about the moment she realized Urban was "the one."
"It was my (38th) birthday, and he stood outside with gardenias at 5 a.m. on my stoop in New York," she said. "That is when I went, 'This is the man I hope I get to marry.'"
And they did, less than a year after Urban's romantic gesture.
While their marriage has had its ups and downs - like when Urban entered rehab just a few months after their "I dos" - Kidman says the highs and lows are all part of their love story.
"Real love happens not when everything is going well but when things are going badly," she said.
"It's when human beings come together if they're going to, in a far deeper way. You're then having to work together, and the 'together' is what it's about. Keith and I talk about that, because that ultimately is the definition of marriage and union and commitment."
Of course, these days even women in their 50s aren't "too old" to keep growing their family.
Recently, actress Brigitte Nielsen welcomed her fifth child at age 54. Friends star Jennifer Aniston, 49, also recently mused about having her first child sometime in the future.
"Who knows what the future holds in terms of a child and a partnership "” how that child comes in ... or doesn't?" she told Elle.
"And now with science and miracles, we can do things at different times than we used to be able to."
And, obviously, no parent is ever too old to adopt a child. But, for now, Urban and Kidman seem "in love and satiated" with their two daughters to look after.
