A new study indicates women who have stronger chins are more likely to cheat.
Dennis Quaid saw this photo of Meg Ryan and proclaimed, "I should have known..."
According to psychologists at Western Ontario University, women with "larger" chins, like former A-list star Meg Ryan can mean more testosterone:
Larger chins on women are often caused by a high level of the male growth hormone testosterone, present in all women in various amounts.
The hormone also increases sexual assertiveness in a woman, a tendency more commonly attributed to males.
The researchers, from four universities across the US and Canada, took a group of young women and questioned them on their sexual histories and fantasies.
These women were then rated by a group of men on their desirability as a life partner.
It was concluded that men will shun women with such masculine features when looking for a long-term partner because they fear being cuckolded.
Psychologists believe it is linked to their evolutionary desire to have a partner who will produce children for only one man.
We're not sure why being more sexually assertive means you're more likely to cheat on your husband with dopey ol' Russell Crowe, but whatever.
