For many women, having children is not a given. A variety of factors, both in an out of our control, mean the subject is a cause of internal debate, consideration and worry for thousands of us.
So those nosy relatives and inappropriate colleagues who bring up the question of why we haven't procreated are, quite frankly, a major bugbear of ours.
Thus we can only imagine what is must be like to be a Hollywood actress over 30, for whom it's pretty much guaranteed that you will be relentlessly quizzed on a.) why you don't have kids, b.) whether you want them and c.) If the answer's no, why the hell not?
Quite when a woman's uterus became the sum total of her being remains a mystery.
But the fact is that no matter how successful and fulfilled these people are, they face relentless pressure about their child free status - along with an unsaid implication that they're somehow missing out by not reproducing.
Kudos then, to figures such as Jennifer Aniston who have made a stand by calling out the baby-grillers.
"I don't have this sort of checklist of things that have to be done, and...if they're not checked, then I've failed some part of my feminism," the Friends actress said recently.
She's joined by a host of stars who either have never felt the need to have children and/or resent the implication that they are less of a person for not having them.
Some of these ladies, like Renee Zellweger and Cameron Diaz, have never been drawn to motherhood and don't regard it as a means of completing them. Others, like Katherine Hepburn, Helen Mirren and Zooey Deschanel, prefer to prioritise their careers. Still more, like Ellen DeGeneres and Portia De Rossi, have thought about it before rejecting the idea. As Jon Hamm's partner, the actress Jennifer Westfeldt says, "The chance that we’ll regret it doesn’t seem like a compelling enough reason to do it".
Whether or not to have kids is a complex issue and there's another category of people, like SATC star Kim Cattrall, who freely admit they may have wanted kids at some point but have figured out it's just not to be.
What draws these women together is their willingness and honesty in talking about being child free, their happiness as fulfilled individuals without the need for kids and their refusal to bow to public pressure on the whole will-she-won't-she motherhood issue. Come see what they have to say:
