The actress told Metro: "I don't really pay attention to that sexy image. It just goes with the character in the movie. At the end of the day, it's all a part of selling a product."
The 29-year-old also revealed that she began to rebel against her parents when she was only five years old.
She said: "It's always been weird because I grew up in a very traditional, Catholic household.
"My parents were very strict but I broke away from that at an early age. I was a feminist when I was 5. These days, I am much more liberal-minded bit I still respect their beliefs."
