"My children ask me to have a baby all the time. And you never know, I could squeeze one more in," she says. "I am missing my third. I'm thinking about it."
Without elaborating on when her pregnancy troubles occurred, she adds, "I had a really bad experience when I was pregnant with my third. It didn't work out and I nearly died. So I am like, 'Are we good here, or should we go back and try again?' "
However, Paltrow, who also recently told InStyle she was open to the idea of having more children, finds more certainty in the man behind her family.
"Regardless of what happens in our marriage, I chose the best father," she says of her rocker husband. "He is so good to the children, and to know that you had kids with such a good man is like a real weight off you. We are committed co-parents, we make all decisions together, and we lean on each other for support as well."
