Drew Scott [SEP] Early life
Andrew Alfred Scott was born on April 28, 1978 in Vancouver, British Columbia, the youngest of brothers James Daniel (by two years) and his identical twin brother, Jonathan (by four minutes). His birth was a surprise to his parents—Jim and Joanne Scott—who had thought she was giving birth to a single child. Their father Jim had emigrated from Scotland as a teenager with dreams of being the kind of cowboy he had seen on television. He worked in the film industry as an actor, stuntman, and assistant director until the late 1970s. It was around that time when he decided to focus on raising his family, and they moved to a horse farm in the nearby town of Maple Ridge.
