Bilson was born in LA, California to a Jewish American father, writer/director/producer Danny Bilson, and a Philadelphia-born Italian American mother, $ex therapist Janice Stango. Her father comes from a show business family; her great-grandfather, George Bilson, was the head of the trailer department at RKO Pictures, while her Brooklyn-born great-grandmother, Hattie Bilson, was a screenwriter and her grandfather, Bruce Bilson, is a film director. Bilson's parents divorced during her childhood, and in 1997, her father remarried Heather Medway, an actress and the mother of Bilson's half-sister Hattie (born December 19, 2001).
Bilson has been noted as having a "self-destructive, rebellious period" during her teen years. When she was thirteen, she and a group of her brother's friends were involved in a car accident, a head-on collision with another car. As a result, Bilson was unconscious for a few days, had a scar above her right eye, and sometimes suffers from migraines and memory loss; she has stated that the experience "changed" her, encouraging her to "stop... getting into trouble" and stopping her from "going down that road".
