Chinese Empress:
She was skinny but her fear was that her body was so used to be skinny that she can't bear it. It was more a psychological problem rather than a practical one.
Probably, I will never know because I was not her doctor, at the time. And I know how celebrities make public statements and you learn years later that it was not true.
Once again, I believe when you said that you heard this information. I just don't believe celebrities so easily. But this is me. I prefer to analyse the situation using observation.
A famous singer could hide her affair with a music producer and her pregnancy, denying it over and over. Years later we knew that, they had a child and got married and even got divorced. When this child was already an adult!!! She manage to hide a child for almost 20 years and she raise that child. Meanwhile she was a successful artist, doing movies and filming successful series, selling millions of albums to date. She is a top artist. Now when you look at her music video, knowing that she was pregnant at that point of time, you see how she managed to hide her belly. But, without knowing it. You would never suspect it. Her mother said that her dress was specially designed to hide her big belly.
So you know, I don't believe in celebrity's public statements.
You might wonder: why did she do all this ? Because she was very young at the time and she was known as the virginal girl next door. In her series, she started as a teenage actor. So she could not let the public know that she was pregnant.
