Brandon Blackstock has passed away at the age of 48.
He was the former husband of the artist Kelly Clarkson.
Clarkson shared on Instagram: “Unfortunately, I need to postpone the remainder of the August Studio Session dates in Las Vegas.
“While I normally keep my personal life private, this past year, my children’s father has been ill and at this moment, I need to be fully present for them.
“I am sincerely sorry to everyone who bought tickets to the shows and I so appreciate your grace, kindness and understanding.”
