Sharp was born in Westminster, London, and was raised traveling throughout Europe and the Southwest of the United States in a caravan, before moving to Devon, England, age eight. He was educated by his mother, a teacher, and his father, who worked in real estate, until the family moved to England. He has a sister, Nicole, also highly successful in her own field.

Upon his return to Devon, he was unable to adjust easily to a traditional school environment, and eventually left England at age 18.
