'Doppelbangers' debunked: Celebrity couples who look alike are no more likely to stay together than pairs who have different faces, study finds

From Kirsten Dunst and Jesse Plemons, to Maggie Gyllenhaal and Peter Sarsgaard, celebrity couples often look weirdly alike. In fact, the phenomenon has coined the term'doppelbanger' – two people with similar facial features who are intimately involved. This has led to speculation that looking similar is somehow conducive to a better or more long-lasting relationship. But researchers in Germany, who used artificial intelligence (AI) to analyse celebrity photos, have found there is no evidence to support this. Celebrity couples who look alike are no more likely to stay together than pairs who have different faces, such as David and Victoria Beckham, and Emily Blunt and John Krasinski, they say.
