Jack Osbourne holds back tears as he explains heartbreaking way he found out dad Ozzy had died

Jack Osbourne has shared a tearful video where he addresses his father's recent passing.

On July 22, the world received the sad news that rock legend Ozzy Osbourne had died at the age of 76.

Osbourne had been battling Parkinson's Disease at the time of his passing but his cause of death was ruled as a heart attack.

His loved ones have been keeping a low profile following Ozzy's death and have been grieving their loss in private, but Jack, Ozzy's son, has now shared a 16-minute long video to YouTube discussing his dad's death in more detail.

The Osbourne family all spent time together in the UK before his death, with the Black Sabbath frontman performing his final gig on July 5 in his hometown of Birmingham.

But prior to Ozzy's passing, Jack returned to his home in Los Angeles and it was while he was stateside that he got the devastating news that his beloved dad had died.

"My father passed away around 10am in the morning UK time, I was in Los Angeles, I had been back for about a week," Jack shared.

"After his show, I stuck around for a week with my kids and hung out at the family house in England and it was awesome, my dad was in an amazing mood."

"It was a lot of fun and looking back now and I am so grateful for that time. My dad was great, he was happy," Jack went on to say of his late father.

Going on to recall the harrowing moment he was told that Ozzy had died, his grieving son revealed: "I woke up in Los Angeles to a knock on my house door at around 3.45am in the morning.

"Someone who has worked for my family for about 30 years now was knocking on my door and when I looked through my window and I saw it was him, I knew something bad had happened. I was informed that my father had passed."

Understandably Jack had 'so many thoughts' when he got the sad news about his dad, but he got some comfort in knowing that his father was no longer suffering.

"I wish he was still with us all, but he was having a rough go and I think people saw that at the show," the 39-year-old added.

Upon getting the news that his dad had died, Jack booked the first flight back to England to be with his family.
