I think she is astonishingly beautiful and there is no need to a) make this about her race, b) be a bitch about her because she won something.
However, as others have pointed out - there is no one single most beautiful person obviously, and the prize could be more accurately named "attractive celebrity who is trendiest at the moment". I prefer the notion of awarding accolades based upon merit, and of seeing the beauty in everyone, not a select few.
