Kelly Clarkson has been quietly dealing with her ex-husband Brandon Blackstock's illness for months - going public with the news in August 2025 after cancelling a series of shows. "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," Clarkson captioned an August 2025 Instagram post, announcing that her Las Vegas residency had been postponed for the time being. Clarkson married Blackstock in 2013.
