Clarkson and Blackstock were married in 2013, but they met years earlier as Blackstock’s father, Narvel Blackstock, owns the music management company that represented Clarkson beginning in 2007. The pair welcomed their first child, daughter River Rose, in 2014 and their son, Remington Alexander, was born in 2016.

In 2020, Clarkson filed for divorce from Blackstock, who also served as her manager.

Clarkson and Blackstock’s divorce was settled in 2022, with Clarkson receiving primary physical custody of their two children while still paying their father $45,000 a month in child support.

While McEntire has yet to speak about Blackstock’s death, her son Shelby shared a tribute to his late half-brother on Friday.

“Words cannot begin to capture the tremendous loss our family has endured. Yesterday, we lost a brother, a father, a grandfather, and a son,” Shelby wrote alongside a photo of Blackstock beaming while sitting on a brown horse in a paddock.

“Brandon Blackstock was an irreplaceable part of our family — funny, bright, and full of life — and he will be deeply missed,” Shelby added. “He taught me so much, leaving behind countless cherished memories that I will hold onto forever.”
