More details about Brandon Blackstock’s death are coming to light.

Following the tragic passing of the talent manager—who shared kids River Rose, 11, and Remington “Remy” Alexander, 9, with ex-wife Kelly Clarkson—at 48, his cause of death was determined to be natural causes related to a diagnosis of melanoma, Silver Bow County Coroner Dan Hollis confirmed to People.

According to a statement shared by the official, “Brandon Blackstock passed away peacefully at his home in Butte, Montana on August 7th under hospice care surrounded by his family.”

On Aug. 7, a rep for Brandon—who is also dad to kids Savannah Blackstock and Seth Blackstock, with his ex-wife Melissa Ashworth—confirmed his untimely death after a yearslong battle with a then-unspecified form of cancer.

“It is with great sadness that we share the news that Brandon Blackstock has passed away,” his rep shared in a statement to NBC News. “Brandon bravely battled cancer for more than three years. He passed away peacefully and was surrounded by family.”
