Arzner would maintain a forty-year relationship with Marion Morgan, a dancer and choreographer who was ten years older than Arzner. Even though she tried to keep her private life as private as possible, Arzner had been linked romantically with a number of actresses, including Alla Nazimova and Billie Burke. It was rumored, though never confirmed, that Arzner also had relationships with Joan Crawford and Katharine Hepburn. She never hid her sexual orientation, nor her identity; her clothing was unconventional for a woman of that time, she wore suits or straight dresses. Morgan choreographed some dancing sequences in some of Arzner's movies, such as "Dance, Girl, Dance".
