Shelley was born in White Plains, New York, and was raised in Greenwich, Connecticut, by her father, William, a chemical engineer who worked as a financial analyst on Wall Street, and her mother, Patricia, a former airline stewardess and Conover Model. She later went to Smith College in Massachusetts and, after graduating, moved to New York where she became one of the highest-paid Supermodels of the 1970s. Later, Hollywood doors opened for her and, in the 1980s, she moved to Los Angeles where she married director/producer Harry Winer with whom she had one daughter, Devon Rose. In 2021, Shelley and Harry sold their Santa Monica home (check out: Great Investment) and, it seems, they moved east to Connecticut to be closer to their daughter, who seems to be based in New York nowadays.
