Try not to make shit up or make assumptions about medical diagnostics without knowing what you are talking about, this barbiegirl wanted to look like something in particular, that does not mean she had any issues with her own body to begin with.
One of the main criteria for most diagnostics include some sort or interference with a significant area of a person's life (social, family, work, etc) in her case her appearance actually draws people to her and to her business, hence there is not distress to the main functions and areas of life.
Here are the official DSM-IV diagnostic criteria for Body Dysmorphic Disorder:
A. Preoccupation with an imagined defect in appearance. If a slight physical anomaly is present, the person's concern is markedly excessive.
B. The preoccupation causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.
C. The preoccupation is not better accounted for by another
mental disorder(e.g., dissatisfaction with body shape and size in
Anorexia Nervosa).
Without even being her therapist it is pretty clear she does not meet the criteria, I know you enjoy taking jabs at actual scientifically proven to work medicine but try not to take ignorant stabs in the dark towards the profession and it's treatments/diagnostics without educating yourself a little bit, it spreads the ignorance when someone states an uncertainty as a fact.
