Ordinarily, I'd agree with that criticism. But the preceding paragraphs talk about her modeling experience (which is valid because it's a fashion-related startup). So to me it seems fair to play off that.
Yeah, that just sounds like journalistic flair to me. You could easily see the same from the other direction, "Mr. Schwarzenegger isn't just a bundle of muscles..."
Maybe the writer felt the need to say she has a pretty face, but didn't know how to say it directly.
