According to Allure magazine, Johansson is very happy with Hartnett, 28. The stars have been together since meeting on the set of the film The Black Dahlia.
Johansson told the magazine, "Josh is very sweet. "He’s a good boy. A great person. I’m very lucky and I’m very happy."
The beautiful young actress, who also starred in the films Lost in Translation and Match Point, added that she has a lot of problems with her image. She explained, "There does seem to be a mistaken belief out there that I am sexually available somehow. I wouldn’t say I’m a serial monogamist. But when I’m in a relationship, I’m in a relationship."
Johansson believes that humans generally have animalistic instincts when it comes to sex. Because of that, she works hard to stay faithful when she is in a relationship. Johansson, 21, also told the magazine that she is happy to have a curvacious body, and that she will never be thin.
