Kelly Clarkson's ex-husband, Brandon Blackstock, has died following a battle with cancer.

On Thursday, a representative for the Blackstock family announced that the talent manager had passed away "peacefully". He was 48.

"It is with great sadness that we share the news that Brandon Blackstock has passed away," they told People. "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."

On Wednesday, Clarkson confirmed she was postponing her Las Vegas residency to spend time with her and Blackstock's children; daughter River, 11, and nine-year-old son Remington.

The Kelly Clarkson Show host revealed for the first time that the Texas native had been "ill" recently.

"Unfortunately, I need to postpone the remainder of the August Studio Session dates in Las Vegas," she wrote on Instagram. "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."

Clarkson has not yet personally commented on the sad news.

The 43-year-old was married to Blackstock from 2013 until their divorce was finalised in 2022.

Blackstock, the son of producer-manager Narvel Blackstock and former stepson of country music superstar Reba McEntire, was previously wed to Melissa Ashworth between 2001 and 2012. The couple shared daughter Savannah, 23, and son Seth, 18.

Over the course of his career, Blackstock managed several high-profile country artists, including Blake Shelton and Rascal Flatts.
