"Twilight" star Ashley Greene showcased her athletic physique in a flowing white evening gown at the 2013 amfAR New York Gala to kick off New York Fashion Week on Feb. 7.
Greene, 26, looked like a Grecian goddess in the sleeveless Giambattista Valli dress that accentuated her gym-toned curves. The 5-foot-5 green-eyed beauty follows a healthy diet, but insists she doesn't starve herself or punish her body with extreme fad diets.
"I don't do the diet thing anymore," said Ashley. "I'm a big believer in feeding your body what it needs. Deny yourself something and you're going to end up shoving your face full of it."
In addition to eating well, Greene works out five to six days a week doing Pilates, cardio exercise, yoga, martial arts and strength-training. While Ashley is slim, she's not emaciated and has desire to be a size zero.
"I don't want a child's body," she said. "I want a woman's body that is extremely fit. It's so much sexier."
Unlike some young Hollywood stars, Greene won't get drunk or act out in public because she doesn't want to set a bad example for her young fans.
"I keep to the ground rules: I’m not going to get drunk at a bar," she said. "There are younger girls who look up to me. So I do my best not to stray too far. I definitely try to be a positive role model."
