The 25-year-old star, who is famous for her sexy avatar, admits following a strict healthy eating regime, which requires her to have five meals in a day combined with vitamin and mineral supplements, reported Contactmusic.
"I eat five times a day and don`t diet, but I do eat healthily - mostly raw and vegan food with no dairy. It`s not always possible with travel and filming, but I try.
"I also take supplements like silica and fish oil religiously,"said Fox.
The `Jennifer`s Body` star believes that femininity is an "attitude" and beauty comes from "simplicity and elegance".
"My definition of beauty is simplicity, elegance and sensuality. I think that when a woman is in harmony with herself and remains true to her values, she will glow naturally. Femininity doesn`t depend on what you wear or how you look. It`s an attitude," added Fox.
