Jack Osbourne, the youngest child of Ozzy and Sharon Osbourne, has broken his silence on the passing of his father.
A little over a month after the Black Sabbath frontman died at 76 years old on July 22, Jack Osbourne posted a YouTube video reflecting on his father and recounting when he heard the tragic news.
On his death certificate, shared by The New York Times, Ozzy Osbourne was said to have died of "out of hospital cardiac arrest" and "acute myocardial infarction."
Around the two minute, 30-second mark of the video below, Jack Osbourne said that he was notified of his father's death by a person who's spent roughly 30 years working for his family.
"I left on the 13th of July, came home, and my dad was great," the 39-year-old said. "He was in a good mood. He was happy. I woke up in Los Angeles to a knock on my house door at around 3:45 in the morning."
Upon seeing the employee, he said he "knew something bad had happened."
"And I was informed that my father had passed," he continued. "Immediately,
I don't know, just [felt] pain, just sadness and pain and just so many thoughts you go through, like feeling sad and frustrated and angry. Like this part of you that's like, 'I have to get there right now.'"
He returned home, and with his mother and older sister, Kelly, attended his father's memorial service on July 30 in Birmingham, England. Ozzy has four other children, including Aimee, his oldest daughter with Sharon Osbourne.
