Kelly Clarkson’s ex-husband, Brandon Blackstock, has died of cancer, multiple outlets confirmed on Thursday. He was 48.

“It is with great sadness that we share the news that Brandon Blackstock has passed away,” a rep for the family told People 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.”

Clarkson and Blackstock share two children: River Rose, 11, and Remington Alexander, 9. The former couple were married for nearly seven years before splitting in 2020.
