Before becoming famous, Scarlett Johansson had a (very subtle) nose job. While this isn't the only plastic surgery she's had, it's probably the best known. At first glance, we can see that she had cartilage removed from the tip of her nose. The great thing about her nose job is how it retained the original shape and character of her nose. Her nose is just it tad bit smaller and more feminine.
