7. Robert Pattinson and Kristen Stewart
With their porcelain skin and dark hair, it was easy for Kristen Stewart and Robert Pattinson to portray vampires in the “Twilight” series. The couple went on to date in real life and were apparently unaware of how similar they looked. Alas, this relationship didn’t last, as Kristen cheated on Robert with film director Rupert Sanders, who also looks quite similar to the actress.
