The actress, who stars as Janet Leigh in upcoming biopic Hitchcock, appeared in a photo shoot for Elle UK's February issue and spoke out about how her figure has earned her a reputation.
She said: "I think any woman who is curvy and wears a gown to an event is, like, super-sexualised."
Johansson said despite her age, her shape earned her comments in the media from the outset of her career.
"I mean, at the time I was 18, 19. I was young," she explained. "I've always been curvy. It runs in the family. "Throw on an evening frock and it's like all of a sudden you have boobs and everyone is like, 'Bombshell!'"
