According to Mann, as a child Hepburn created an identity she called Jimmy. This was who Hepburn truly believed herself to be – a boy named Jimmy Hepburn. Mann explains that Hepburn actually had 3 personalities: Jimmy, Kath, and Kate. Jimmy was her true self, Kath was the female she presented to her family, and Kate was the actress and Hollywood legend we all knew. It’s some very interesting insight.
Honestly, I think that means she had Multiple Personality Disorder, but of course, that she thought of herself as having a few genders doesn’t make her trans – just interesting.
Interestingly, the title of the book this idea comes from is called Kate: The Woman Who Was Hepburn.
