HOLLYWOOD: Sienna Miller wishes she were fatter. The 27-year-old actress told New York Magazine that she admires plus-size models. “I sincerely believe that that’s more beautiful than someone who is poker-thin,” she told the magazine. “I really do. I would love to have boobs to go with my hips, but I don’t. That’s just not the way the cookie crumbled.” Miller, who is currently starring on Broadway in “After Miss Julie,” modeled to pay the bills before hitting the big time. But despite her looks, she never fit the tall, skinny model mold. “I was, like, the short, funny one that they booked to make the other girls laugh,” she said. “And to make them look taller.”
