The 38-year-old former Spice Girls singer - who has three daughters, Phoenix, 15, with ex-husband Jimmy Gulzar, Angel, six, with Eddie Murphy, and Madison, two, with current spouse Stephen Belafonte - would love to have a son but thinks she and her spouse, who also has nine-year-old Giselle from a previous relationship, would have another girl.
Asked if she wants more children, she said: "I'd like to, but I'm not sure. I always say just one more. I want to have that boy, but knowing my luck I'll have another girl."
The 'America's Got Talent' judge loves relaxing at home with her kids, but also enjoys taking them to work with her as she thinks it is "good" for them to see the importance of having a job and working hard.
She told Britain's OK! magazine: "We love hanging out by the pool and having a barbecue, or we take a walk around Malibu, go to Venice Beach or Santa Monica Pier. We have a movie theatre upstairs that we hang out in.
"The girls love coming on the set of 'America's Got Talent' too. It's good for them to see how hard the auditioning is, and I think it sets a good precedent for the kids to see that you're not just staying at home, that you're being creative and you are out working, earning money and enjoying what you do."
