So how did the actress make her svelte physique more voluptuous? "Soy helps you become curvy because it has estrogen in it," she said. "So what I would do — and this is really gross — is buy cartons of soy ice cream, microwave it and drink it. It was disgusting, [but] wait [until] you see my boobs in the movie."

The health-conscious star described her weight gain as "a form of torture."

"You put on all this weight, and then you're in the South where it's really hot and muggy," she said. "And you're putting on girdles to suck you in!"
