Izzie is fully aware of how good-looking she is ("I'm a pretty girl ... that's just a fact.") and has deliberately used it to her advantage in a world where she knows she will be objectified (modelling to pay for med school).
Addison is semi-aware of how good looking she is but it still takes her by surprise every time it's brought up to her because in her mind, she's still a band geek with braces and a lisp. Her good looks are a disadvantage in her head because she feels she will be taken less seriously as a doctor for them.
