The family of Brandon Blackstock, Kelly Clarkson’s ex-husband and the father of her two children, shared the tragic news that Blackstock has died at 48 from cancer.

“It is with great sadness that we share the news that Brandon Blackstock has passed away,” the family said in a statement. “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.”

Blackstock was Clarkson’s former talent manager. He also managed Blake Shelton and Rascal Flatts. Blackstock had a producer credit on “The Kelly Clarkson Show” as well as the television special “Blake Shelton Live: It’s All About Tonight,” according to IMDb.

The announcement of Blackstock’s death came a day after Clarkson, 43, said she was postponing the remainder of her August “Studio Sessions” shows at the Colosseum at Caesars Palace during Blackstock’s illness to be with her children.

“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,” she wrote on Instagram on Aug. 6.

Blackstock’s father, Narvel Blackstock, is also a talent manager and founded Starstruck Entertainment in 1988. He was previously married to country music legend Reba McEntire, Brandon Blackstock’s stepmother.

“Brandon’s been my son forever it seems. Although he’s my stepson, I still love him like he’s my total — my blood, so I’m praying for ‘em both ‘cause I love ‘em both,” McEntire told “Entertainment Tonight” at the time of his divorce from Clarkson.

Clarkson and Blackstock, who separated in 2020 after seven years of marriage and finalized their divorce two years later, share daughter River Rose, who was born in 2014, and son Remington Alexander, born in 2016.

Blackstock also had two children from a previous marriage, son Seth Blackstock and daughter Savannah Blackstock.

When Clarkson filed for divorce from Blackstock, she cited “irreconcilable differences.” She told People in 2024 that she was grateful to be able to turn to music during this time.

“I cannot express how appreciative I feel for having that kind of healthy outlet. Because the level of depression and things that come with divorce or grieving is extraordinarily hard. You feel alone, and it’s just a blessing to be able to have that outlet for those emotions that are overwhelming.”

Clarkson lives with her children in New York City, where she also hosts her daytime talk show, “The Kelly Clarkson Show.”
