In a recent interview, Jack opens up about this relationship with older sister Aimee Osbourne, and shared where they stood before reuniting at their father Ozzy Osbourne's funeral last month.

Ozzy and his wife, Sharon Osbourne, shared three children: daughters Aimee, 41, and Kelly 40, and son Jack, 39. The late rocker also had three other children — Elliot, Jessica and Louis — from his first marriage to Thelma Riley.
