The ‘American Idol’ alum shares two children with her late ex-husband, Brandon Blackstock, and has always made them her top priority.

After wiping the tears from her face, the "American Idol" alum cracked a joke to her fans about the magic of "compartmentalization."

Kelly Clarkson’s ex-husband, Brandon Blackstock, died from skin cancer three years after being diagnosed. Dan Hollis, the coroner for Silver Bow County in Montana, confirmed Blackstock had died from melanoma in a Monday statement to People magazine. The manner of death was natural causes.
