Is it an act of extreme self-esteem hubris to date one's own clone? Keira Knightley is a lovely young lass. And talented to boot. But seeing her here, dressed strangely similarly to her doppelganger boyfriend Rupert Friend just amplifies the "I'm fucking myself" quotient of their relationship. I've heard about seeking a mother or father figure, but seeking out your own figure is just weird.
