Pretty much all women, celebrity or not, come crashing down to earth when you live with them. That's when you realize that she's just a basic bitch from Fort Worth, Phoenix, etc. Her ability to accept criticism then becomes important, since she'll need to acquiesce to your headship to make the relationship work. Most of these celebrity women are incapable of making such an accommodation, which is why the majority of them get divorced.
