Why we like friends with familiar faces
We are more likely to approach strangers with whom we share a physical resemblance - as is the case with Eva Longoria and Victoria Beckham, who became firm friends after the former Spice Girl moved to Los Angeles with her husband David. Researchers from Wilfrid Laurier University in Ontario, Canada, made the discovery after asking 356 students, who did not already know each other, to attend a series of lectures in small rooms, forcing them to sit next to someone.
The results of the study showed that students who wore glasses were more likely to sit together as were those who had similar length or colour hair, the same colour eyes, or similar body proportions, the Daily Mail reported.
In a second test, a female student carried out three-minute interviews with 72 female students.
Those who had the same colour eyes as the interviewer, sat closer to her, as did those with similar hair colour and length and a similar body shape.
Finally, researchers presented the students with eight pictures of people who differed in terms of sex, race, hair and whether they wore glasses.
After asking whom they would rather sit next to, the participants once again gravitated towards people who most resembled themselves.
According to consultant psychologist Ingrid Collins, if we look in the mirror we see a familiar image, so someone who looks like us can remind us of our own self or our family. This makes us feel that we know those people a lot better than we actually do, giving us a sense of familiarity.
Beckham and Miss Longoria were regularly pictured together watching David when he played for LA Galaxy.
To further cement their friendship, the Beckhams made the former 'Desperate Housewives' star the godmother to their daughter Harper.
Other celebrity lookalike friends include blonde broadcasters Holly Willoughby and Fearne Cotton, and Paris Hilton and the equally petite Nicole Richie.
The study has been published in the Personality and Social Psychology Bulletin journal.
