I don't know if their bodies are real or not but Scarlett and Jessica Biel have the hottest, most natural looking figures in movies. They both need quite a bit of work to make their faces look like the are in the super hot category though. Especially Scralett, you look at her face and even with makeup you can see all the pitting and patchiness to it. Biel too looks really plain while actresses like Jessica Alba look hot 24/7, I don't think there has ever been a bad pic of her.
Was Scarlett the ugly duckling? At 15 you can tell where most girls are headed in the looks department unless they get some surgery or the benefit from excellent make-up.
