Johansson: 'Monogamy is unnatural'

Scarlett Johansson has revealed that she does not believe monogamous relationships are natural.

The actress, who married Ryan Reynolds last week, said she understands why people have open relationships, although she would not consider one herself.

She is quoted as saying: "I'd never want to be in an open [relationship]... [but] I don't think monogamy is a natural instinct for human beings."

Johansson added that she dislikes the way her own sex life has been portrayed in the media.

'I don't like talking about my personal relationships - it always ends up kicking you in the face," she said.
