Clarkson, the "American Idol" star who shared two children with Blackstock, had just announced she was stepping away from concerts to support her family.

Kelly Clarkson postponed August dates of Caesars Palace residency in Vegas to care for her kids amid the death of ex-husband Brandon Blackstock.

Kelly Clarkson was absent from her talk show earlier this year because her late ex-husband, Brandon Blackstock, was ill with cancer.
