Jack was Ozzy's only son with Sharon Osbourne, whom the rocker married in 1982. The couple also shared daughters Aimée Osbourne and Kelly Osbourne.

While Jack and his other older sister, Kelly, 40, garnered fame after starring in MTV’s “The Osbournes” with parents Ozzy and Sharon, 72, Aimee chose not to participate in the show during its four-season run from 2002 to 2005.

Jack recalled feeling as though Aimee "wanted to be relatively private and obscure" throughout the Osbourne family's 2000s reality TV era
