Brandon Blackstock’s death was not an easy one.

According to his death certificate, the ex-husband of talk show host Kelly Clarkson suffered from multiple seizures before his passing.

The former stepson of Reba McEntire had been fighting skin cancer – malignant melanoma – for three years. 

He died last week at his home in Butte, Montana at the age of 48.

People acquired the death certificate from the Butte-Silver Bow County Clerk and Recorder’s office on Thursday. His death is recorded as due to ‘natural causes.’

The rodeo producer reportedly had ‘significant conditions contributing to death but not resulting in the underlying cause.’

No autopsy was performed on Blackstock and he was cremated, according to the death certificate.

Brandon was married to Clarkson from 2013 until 2022; during their union, they had two children, daughter River Rose, 11, and son Remy, nine. 

The late music manager was also father to daughter Savannah, 23, and son Seth, 18, both of whom he shared with his first wife Melissa Ashforth. 

Blackstock also became a grandpa in January 2022 when his daughter Savannah welcomed her first child, a son named Lake Lee, with her husband Quentin Lee. 

Just one month before Brandon’s death, his daughter Savannah had announced that she was expecting a second child, a baby girl, with her husband. 

Meanwhile, the father of Clarkson’s former assistant Brittney Marie Jones, who was dating her ex-husband Blackstock before his death, claims they were ‘soulmates.’

Jones’ dad broke his silence on the matter in a Facebook post that has since been made private.

‘Yesterday we lost a good man, Brandon Blackstock, my daughter’s soulmate, and I considered him my son,’ he wrote on a now private post, seen by Page Six.

‘My sincere condolences to Brittney Jones and family. We’re sure going to miss your funny humor. R.I.P hoss!’

Blackstock’s online obituary, released on Tuesday, revealed that he had been in a relationship with Jones and was quietly building a new life with her in Montana, previously unknown to many fans.

‘After more than 20 years in the music business, Brandon found his way back to the mountains and the cowboy way of life he always wanted to live,’ the obituary read. ‘He found a homestead and a love in Butte, Montana.’

It went on: ‘Brandon, along with his beautiful and loving partner in life and business, Brittney Marie Jones, started building a life, building companies, and working tirelessly to create Headwaters Livestock Auction and what will live on as his legacy, The Valley View Rodeo in Bozeman, Montana.’

In a bombshell revelation, a December 2024 report on Blackstock and Jones’ rodeo business listed Jones as Clarkson’s ‘former assistant.’

A prior LinkedIn profile for Jones highlighted in the report reveals she served as an executive assistant to Brandon Blackstock as well as an assistant to Kelly Clarkson while Blackstock managed the singer.

‘I successfully assistant managed day to day for artist, Kelly Clarkson under manager, Brandon Blackstock in Los Angeles for music and television,’ the profile read, according to The Sun.

‘After a change in management for Ms. Clarkson, I transitioned to Executive Assistant for Mr. Blackstock’s cattle operation in Montana, where I currently run the office and handle administration work.

‘I also currently fulfill personal assistant duties for Mr. Blackstock.’

Jones’ LinkedIn also identifies her as the Executive Assistant of V Bar V Cattle Co. LLC — formerly Vintage Valley Ranch — one of Blackstock’s companies, further tying her to his post-divorce life in Montana.

A representative for the family confirmed Blackstock’s death in a statement on Thursday, August 7, which read: ‘It is with great sadness that we share the news that Brandon Blackstock has passed away.

‘Brandon bravely battled cancer for more than three years. He passed away peacefully and was surrounded by family.

‘We thank you for your thoughts and prayers and ask everyone to respect the family’s privacy during this very difficult time.’

In a statement shared online on Wednesday, August 6, Clarkson revealed a health-related issue with Blackstock forced her to postpone her Las Vegas residency.

‘Unfortunately, I need to postpone the remainder of the August Studio Session dates in Las Vegas,’ she wrote.

‘While I normally keep my personal life private, this past year, my children’s father has been ill and at this moment, I need to be fully present for them.

‘I am sincerely sorry to everyone who bought tickets to the shows and I so appreciate your grace, kindness and understanding,’ she concluded.

The exes — who split in 2020 and finalized their divorce in 2022 — shared daughter River, 11, and son Remy, nine.

In addition to Kelly and their kids, the talent manager is also survived by his pregnant daughter Savannah, 23, and son Seth with ex-wife Melissa Ashworth.
