Did Audrey Hepburn really cut her hair in roman holiday?

Yes, Audrey Hepburn did indeed cut her hair for her role in Roman Holiday. It was actually the studio that suggested she do so. At the time, Hepburn had long, brown hair, but the studio wanted her to look more like a young boy for the role of Princess Ann. Hepburn was hesitant at first, but she eventually agreed and had her hair cut into a short, pixie-like style. The new haircut was a success and Hepburn's look in the film became iconic.
