Being hailed as one of the world`s sexiest women, actress Scarlett Johansson says she never wanted to be taken as a sex symbol. Johansson, 27, said she wanted to be known for her actress prowess, reported Daily Express. “I never wanted to be a sex symbol, I wanted to be a character actor. But I think women who are curvy can be pigeonholed in that bombshell thing. What can I do about it? “I`m never going to be rail-thin. Everyone in Hollywood is so damn skinny and you constantly feel like you`re not skinny enough,” she said. Johansson, who was seen flexing her muscles as the Black Widow in “Iron Man 2”, said she had to watch her calorie intake a little closer for the superhero flick. “You`re training and doing all that stunt work so you eat a lot of green things. I spent a lot of time in the gym because of all these huge choreographed fight scenes, and I was happy to do that,” she said.
