The mother-of-two, 38, has two kids with by her 42-year-old spouse: daughter Willow, 6, and son Jameson, 9 months.
But despite previous speculation they could yet add to their adorable brood, the chart-topper, whose real name is Alecia Moore, has now emphatically ruled out the possibility.
Asked if she would like more children, she told America’s OK! magazine: “Nope. One is one, and two is 10. When Willow was born, I stayed home for six months, and [with Jameson] I didn’t stop. So it’s been a lot – but I love it.”
Pink’s marriage has been rocked by tough periods in recent years, with her and motor racer Hart even separating during low moments.
Addressing their current status, she said: “I think right now everything is good again. But any long-term relationship is all over the place. You just take it day by day. You’re like, ‘I love you, you’re wonderful’. And the next day you’re like, ‘I never want to see you again. Come here [laughs.]”
Pink's interview comes as she prepares to launch her seventh album, and a new short film called On the Record: P!nk — Beautiful Trauma.
In a PEOPLE exclusive clip, the singer talks about her life before and after marriage and children.
“I would like to put everything I am and everything I have into everything that I do,” she says. “I’d say the hardest part is just trying to figure it all out. I signed up for this when I was 16 and now I have children and I have a marriage.
"I just want to always make sure that I’m doing right by them. It’s not a simple puzzle anymore — it’s not just me.”
Fans are excited about the star's upcoming Aussie tour - with the country's enduring love affair already proven by her first single from the album, What About Us, flying to the top of the charts.
