Osbourne died on Tuesday at 76, just weeks after he and Black Sabbath performed at their farewell Back to the Beginning concert earlier in July.

Ozzy and Kelly - whom the heavy metal pioneer shared with wife Sharon, along with daughter Aimee and son Jack - were close. Fans first got a look at their family dynamic on The Osbournes, a reality show that ran on MTV for three years in the early 2000s.

Black Sabbath guitarist Tony Iommi said he thinks bandmate Ozzy Osbourne was "determined" to play the group's farewell show and "really just held out" to do so weeks before his death.
