With an accompanying photo that highlights the fact, we can see Pitt matching beachy locks with Jennifer Anniston, getting pale and moody with Angelina Jolie, and even adopting the same pout and hair style as former girlfriend Gwenyth Paltrow.
The post has gone viral, and although the hilarious, there is actually an extremely logical and scientific reason behind the constant shape shifting and look stealing.
By replicating familiar looks, the women Brad Pitt dates are more likely to find him attractive. According to new research published in the Evolution and Human Behaviour Journal, women unconsciously seek partners who look like their brothers.
"[Our findings] were not a rule or true of every woman but we do find that, at levels greater than chance, partners did show some subtle resemblance to the women's brothers," said lead researcher Tamsin Saxton when talking to The Independent. With “clear evidence for perceptual similarity in facial photographs of a woman’s partner and her brother”, the research puts forward that women are 27 per more likely to be attracted to a man who looks like her brother.
Saxton suggested that she originally commenced her research following reports that women were attracted to partners who look similar to their parents. Building on these reports, her findings narrowed in on the brother relationship, whilst also reached the concluding that "familiarity seems to be attractive".
