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.

A ree Osbourne vowed to look after her mother-in-law, Sharon Osbourne, in the wake of Ozzy Osbourne’s death. The wife of Jack Osbourne posted a poignant tribute to Instagram a few days after the Black Sabbath legend’s life was remembered with a funeral procession and memorial service at his Buckinghamshire estate.

"We don't have a great relationship. She'll be the first to tell you that," Jack said on the "Disrespectfully" podcast.
