Jack Osbourne has paid a heartbreaking tribute to his father Ozzy, just days after he was laid to rest in Buckinghamshire.

The Black Sabbath frontman, who was diagnosed with Parkinson’s disease in 2019, passed away at the age of 76 on July 22 surrounded by his family. 

According to his death certificate, the singer died from an ‘acute myocardial infarction’ and ‘out of hospital cardiac arrest’.

Speaking about his father’s passing on social media for the first time, Jack expressed that his ‘heart has hurt too much’ and shared heartfelt words to honor his dad.

Jack, 39, wrote: ‘I haven’t really wanted to post anything since the passing of my father. My heart has hurt too much. 

‘I’m going to keep this brief because he truly despised long, rambling talks. He was many things to many people, but I was fortunate and blessed to be part of a very small group that got to call him “Dad”.

Commenting on his father’s passing for the first time online, Jack shared that his ‘heart has hurt too much’ accompanied by tender words to remember his father.

‘My heart is full of so much sadness and sorrow, but also so much love and gratitude. 

‘I got 14,501 days with that man and I know that is such a blessing. I think this quote best describes my father.

‘Hunter S. Thompson once remarked: “Life should not be a journey to the grave with the intention of arriving safely in a pretty and well-preserved body… but rather to skid in broadside in a cloud of smoke, thoroughly used up, totally worn out, and loudly proclaiming,‘Wow! What a ride!’”

‘That was my dad. He lived and he lived his life fully. I love you dad.’

Ozzy was laid to rest on the grounds of his own mansion in Buckinghamshire last week during a private funeral attended by his family and a host of rock royalty. 

His widow Sharon, 72, and their children were joined by stars including Marilyn Manson and Ozzy’s lead guitarist Zakk Wylde during the event at the family’s 250-acre estate near Gerrards Cross. 

His passing came just weeks after he appeared on stage for his farewell concert at Villa Park stadium in his native Birmingham.

Jack gave no clue that Ozzy’s demise would be so soon. He said in an interview: ‘Listen, everyone gets old, everyone slows down as you age – it’s part of the journey. I just try and support him as much as I can. We all do’

Jack said watching his dad on stage was ‘very emotional. Just to see him up there doing his job was great. We were all tearing up.’

His dad, however, remained nonplussed and replied with his typical blunt wit: ‘Lot of f***ing good that does me. I’m retired now!’

In the interview, Jack gave no clue that Ozzy’s demise would be so soon. He said: ‘Listen, everyone gets old, everyone slows down as you age – it’s part of the journey.

‘I just try and support him as much as I can. We all do.’

The concert – three weeks before his death – saw him reunite with his original Black Sabbath bandmates for the first time since 2005.

More than 42,000 fans packed into the venue for the Back To The Beginning show, during which he told the crowd in his final speech: ‘You’ve no idea how I feel – thank you from the bottom of my heart.’

Official documents listed three causes of death for the rock legend. This included an out of hospital cardiac arrest, acute myocardial infarction and coronary artery disease and Parkinson’s disease with autonomic dysfunction. 

In a statement shared last month, Ozzy’s family said he died ‘surrounded by love’, adding: ‘It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning.’

Kelly, 40, who starred in the 2000s reality series The Osbournes, shared a post on her Instagram story on Monday thanking fans for their support.

She said: ‘I’ve sat down to write this a hundred times and still don’t know if the words will ever feel like enough… but from the bottom of my heart, thank you.

‘The love, support, and beautiful messages I’ve received from so many of you have truly helped carry me through the hardest moment of my life. Every kind word, every shared memory, every bit of compassion has meant more than I can ever explain. 

‘Grief is a strange thing – it sneaks up on you in waves – I will not be ok for a while – but knowing my family are not alone in our pain makes a difference.

‘I’m holding on tight to the love, the light, and the legacy left behind. Thank you for being there. I love you all so much. – Kelly #BirminghamForever #OzzyForever.’

Kelly spoke about how well Ozzy was doing in a poignant last interview just two weeks before he died.

Just two days before she got engaged to Sid Wilson at Ozzy’s final performance with his band in Villa Park, Birmingham, Kelly said her father was feeling ‘amazing’.

She said: ‘My dad is amazing! He’s so excited for his final show on Saturday. There is all the nerves and all the excitement. 

‘He’s sailing through everything, and the rehearsals have been incredible. It’s all about him. It’s going to be a very emotional moment.’
