Rachel Weisz has branded thin women "un-feminine".The British actress has urged Hollywood stars not to feel under pressure to diet, insisting women without curves are less feminine and not very attractive. Rachel said: "If you diet away your curves, you are dieting away your femininity. I enjoy dressing up, but you can do that without flagellating your body."The 36-year-old loved the attention her breasts received when she appeared in a low-cut gown at last year's Venice film festival. Rachel, who had given birth just three months earlier to son Henry, said: "Luckily the empire line was in fashion. My breasts were still pretty huge and the dress just flowed, bypassing most of my body."So it was a great moment for me - I coincided with fashion in a good way."Rachel, who lives in New York with director Darren Aronofsky, says she loves Manhattan because she can enjoy a quiet life. She explained: "I love Manhattan, it's an island full of immigrants. I can live a relatively normal life there. New Yorkers are always in too much of a rush to be star struck."
