However, writing in Scientific Reports, Tea-makorn and Kosinski describe how they found no evidence for couples looking more alike as time passed. They did, however, look more alike than random pairs of people at the start of their relationship.

The findings suggest that celebrity couples such as Benedict Cumberbatch and Sophie Hunter, and Gisele Bündchen and Tom Brady, will not grow to look more alike over time, but rather went for partners with similar features to themselves. Tea-makorn said people may seek out similar-looking partners, just as they look for mates with matching values and personalities.
