Ivy Nicholson was born Irene Nicholson in Queens, New York to working class Irish Catholic parents. She started modeling at the age of 16, and became very successful, gracing the covers of Vogue and Elle. In those days there was not much in the way of work for older models, so when she turned 30, Ivy sought out acting roles, eventually landing in Andy Warhol's Factory.
