The 'Black Dahlia' star seems to be of the same opinion as Sienna Miller who, after insulting the residents of Pittsburgh by associating the name with the town with a thing that we do while in the loo and that begins with 'sh-', said 'I don't believe in monogamy. We are all f**king animals'.

Scarlett Johansson also said in a very recent interview that she, too, believes that monogamy is contrary to the human basic instincts. 'I do think on some basic levels we are animals, and by instinct we kind of breed accordingly', the starlet said.

But she insists that she is not at all that promiscuous as the media sometimes wrongfully represents her. The actress talks about her private life, claiming that, as long as she is in a serious relationship (as is the case now with fellow co-star Josh Hartnett), she does her best to suppress those instincts. 'There does seem to be a mistaken belief out there that I'm sexually available somehow - which is not to say that I'm not open-minded about sex, yet I wouldn't say I'm a serial monogamist, either', Scarlett explained.

In the same interview, published in the latest issue of 'Allure' Magazine, Scarlett also takes the opportunity to offer some piece of advice to all her younger (or older) fans out there. Speaking about being tested for HIV, the actress tells the world that everybody should get the test done at least twice a year, because only this way people can be more socially aware.
