Kelly Clarkson canceled her appearance at the Band Together Texas Benefit following the death of her ex-husband Brandon Blackstock. She and the late music manager share daughter River and son Remington.

‘Brandon Blackstock passed away peacefully at his home in Butte, Montana on August 7th under hospice care surrounded by his family,’ Silver Bow County Coroner Dan Hollis said, confirming that Blackstock’s cause of death was melanoma, a form of skin cancer and that the manner of death was natural causes.

The singer was scheduled to appear at Miranda Lambert and Parker McCollum's Band Together Texas event taking place on Sunday to support those affected by the floods in July. However, Clarkson has canceled as a result of Blackstock's death last week, according to a since-expired Instagram Stories post from the concert's organizers.
