The 'Something Borrowed' actress, who stuns on the cover in a black and gold dress, stressed her desire to be a good role model to young women, reported Us magazine.
"If there is one thing I will never have, it is an eating disorder," the mother of two said.
"I won't have girls -- even if it is just one or two who care -- thinking that. Because it is a serious sickness, not something to plaster on the cover of a magazine. And I am the opposite," she added.
"I want girls to love themselves. I want them to feel good about who they are... The thing is, I'm lucky because I was loved (during that time). But I have seen so many young women who can't feel good about themselves because they just don't have that love.
