The 22-year-old actress - who is widely considered to be one of the most beautiful women in Hollywood - insists even she has days when she feels overweight, just like every other girl her age.
She said: "I have fat days and accept that I'm never going to be real thin." This isn't the first time Scarlett has confessed to having issues about her looks.
She recently admitted she doesn't always feel desirable and often finds it tough living up to her glamorous image.
She revealed: "I know what I look like when I wake up in the morning after three hours sleep.
"Sometimes I feel, 'OK, this is a good day', and other times I wake up and think, 'Oh my God, I need a hat today.'" Despite her concerns, Scarlett is prepared to strip and show off her desirable body on the big screen.
'The Black Dahlia' actress said: "I'm not opposed to doing nudity, it would just have to be the right project."
