Osbourne was born in London to heavy metal singer Ozzy Osbourne of Black Sabbath, and his wife and manager, Sharon ( Levy). He has two elder sisters, Aimee and Kelly Osbourne, as well as two paternal half-siblings, Louis John Osbourne and Jessica Hobbs, from his father's previous marriage. Osbourne has stated that his childhood was "perfectly happy and contented". For the first six years of his life, he lived in the Chiltern Hills in Buckinghamshire. When he was six, his parents moved the family to Los Angeles, but a year later the family returned to Buckinghamshire. When Osbourne was 11, the family moved back to Southern California, but this time to Beverly Hills. In spite of moving so many times at a young age, Osbourne did not find it disruptive. His maternal grandfather was Don Arden (Harry Levy), an English music manager.
