Ozzy Osbourne was a heavy metal icon. He was also an unlikely reality TV pioneer on "The Osbournes," with his wife Sharon and kids Kelly and Jack.

Transformed by 'The Osbournes' from bird-biting Prince of Darkness into one of TV's quintessential bumbling dads, Osbourne helped usher in a wave of image makeovers with unexpectedly lasting ripples.

The heavy metal legend passed away on Tuesday, July 22, surrounded by family, weeks after a final performance with Black Sabbath. He leaves behind his wife, Sharon, 71, and six children: Aimee, 40; Kelly, 39; and Jack, 38, whom he shares with Sharon, as well as son Louis, 49; Jessica, 51; and Elliot, 47, from his first marriage to Thelma Riley.

Ozzy Osbourne, the hellraising frontman of Black Sabbath and reality TV star, has died aged 76. The news was confirmed via the Associated Press on Tuesday, who included a statement from the Osbourne family:

Ozzy Osbourne, the front man for Black Sabbath, died July 22, just weeks after he reunited with his bandmates for a farewell concert in England. He was 76.

Kelly Osbourne made her first public comments on Thursday, two days after the death of her father, rock legend Ozzy Osbourne. "I feel unhappy I am so sad," Kelly Osbourne wrote in an Instagram story.
