The couple, who will celebrate their fifth wedding anniversary on Nov. 18, are the parents of five-year-old Dylan, and Carys, two.
And 61-year-old Douglas, who is 25 years older than his wife, is starting to feel that it's time he stopped reproducing.
On the question of having more children, Zeta-Jones says, "You better ask Michael. He said he doesn't wanna be too old where I have to push him in a wheelchair as well as a stroller. He said it, not me!
"I would (have another baby). I was one of three, so I think the balance is a really good dimension for me. Hey, if it happens, but I'm not planning anything imminently."
Douglas also has a 26-year-old son Cameron, from his first marriage to Diandra Luker.
