Andrews was born in Lambeth, London to Nirmala, a Psychologist, and Stanley Andrews, a businessman, both Malayali Nasrani immigrants from Kerala, India. He was brought up in Wandsworth in the Methodist denomination of Christianity. Andrews described his upbringing as "very repressive". At the age of 16, while at Emanuel School, he fell in love with his then-30-year-old mathematics Teacher, Geraldine Feakins whom he moved in with to escape his abusive home; their son, Jaisal, was born seven years later, in 1992. Andrews was shunned by his parents after this and they died before a reconciliation. He has stated that he forgives them now.
Andrews was in a relationship with schoolteacher Geraldine Feakins from 1985 to 1991. They fell in love while Andrews was aged 16. He moved into her home in order to escape an abusive household. His parents shunned him following this and they died without reconciling with their son. Naveen had a son, Jaisal Andrews, in 1992. He was later in a relationship with Actress Barbara Hershey in Los Angeles, starting in 1998. The couple separated briefly in 2005 and, during that time, Andrews had a son with Czech-French Actress Elena Eustache. He and Hershey later reconciled; however, in May, 2010, they announced that they had separated six months earlier. He has been involved in an ongoing custody dispute with Eustache over their son, and on January 7, 2009, Andrews was granted sole legal and physical custody of the child.
He plays guitar and sings, while tap-dancing to his own tune as a hobby. He became a naturalised U.S. citizen on 27 May 2010.
