Monroe's Mother
It's said that for years, Gladys claimed that Marilyn was her daughter to other people at her hospitals. Of course, no one believed her. Since the two had a strained relationship as well, the daughter never visited to prove Gladys' story was true all along.
A Character
Many historians referred to Marilyn Monroe as a character, as did Marilyn herself. She often talked about Marilyn as a third person. Those who worked with her recalled being surprised when Monroe would edit a script with a phrase like "Marilyn would never say that."
