A new study appears to show that some women are biologically programmed to be bad mothers.
But why are so many of them celebrities, I hear you cry? Well, that's not something the researchers at Virginia's University of Richmond have tackled.
However they do claim to have found that some women have a "bad mothering" brain switch.
Craig Kinsley, an associate professor of psychology and neuroscience at the University of Richmond, says his study discovered that women develop a cluster of brain cells, called maternal neurons, while they are pregnant.
Once the baby is born, these brain cells are "switched on" - triggering good or bad parenting skills and behaviour.
Kinsley told NewsCore: "We believe that a certain number of these 'maternal neurons' need to be 'switched on' for good mothering to take place.
"Our research showed that the mothers with fewer than this number of 'maternal neurons' tended to neglect or abuse their offspring, while those animals with the lowest numbers actually savaged or killed their own young."
However some have disagreed with the study's findings, saying maternal behaviour is more complicated than a simple "switch".
Alison Fleming, director of the Centre for the Study of the Psychobiology of Maternal Behaviour at the University of Toronto, said: "There is no single factor that determines maternal behaviour.
"The idea that a woman's brain is 'hardwired' in such a way that she will abuse her children and that it is not within her power to refrain from doing wrong is based on a misunderstanding of neuroanatomy.
"All behaviour is dictated by the brain, but the brain is formed in interaction with our environment."
It does seem a little too easy to blame a cluster of brain cells for bad mothering. Whatever happened to free will?
