Kelly Clarkson’s ex-husband is Brandon Blackstock, and a lot has happened with him over the past few years, both personally and legally.

Quick Scoop

  • Kelly Clarkson married talent manager Brandon Blackstock in 2013 and filed for divorce in 2020, citing irreconcilable differences.
  • Their divorce was contentious, involving custody, large support payments, and later a major financial ruling in her favor over business deals he made as her manager.
  • In August 2025, Brandon died at age 48 after more than a three-year battle with cancer; Kelly paused her Las Vegas shows to focus on their kids during his illness.

Their Relationship and Divorce

  • They first met in 2006 and eventually married in 2013, later welcoming two children together.
  • In 2020, Kelly filed for divorce, and she was declared legally single in 2021; the divorce was fully finalized in March 2022.
  • Court documents show she agreed to pay a one-time settlement of just over $1.3 million, plus significant monthly spousal and child support for a time.

Kelly has spoken publicly in a careful, emotional way about how difficult the split was, especially because of their children, but she has avoided detailed mud-slinging in mainstream interviews.

Lawsuits and Money Drama

After the divorce, things got more complicated on the business side:

  • Brandon (and his family’s company Starstruck Management) had been managing Kelly’s career, including deals for shows like The Voice and brand partnerships.
  • A California labor ruling found that he unlawfully procured certain deals that should legally have been handled by a licensed talent agent, not a manager.
  • As a result, he was ordered to pay Kelly about $2.6 million in compensation related to those commissions.
  • Brandon and his company later formally denied “each and every allegation” in filings and sought to have that decision reversed, keeping the legal battle going for some time.

So when people online ask “Kelly Clarkson ex husband what happened,” they’re usually referring to this mix of messy divorce, big money disputes, and later, his illness and death.

His Illness and Death

  • In mid-2025, Kelly announced that her children’s father was ill and postponed the remainder of her Las Vegas residency so she could be fully present for them.
  • Shortly afterward, the family confirmed that Brandon had been battling cancer for more than three years.
  • He died in August 2025 at age 48, surrounded by family, according to statements shared with outlets like PEOPLE and CNN.

Kelly’s public comments around that time focused on protecting her kids’ privacy and thanking fans for their understanding, rather than revisiting their past conflicts.

How It’s Shaped Kelly Now

  • Post-divorce and after his passing, Kelly has channeled a lot of her emotions into her music and her talk show, where she’s talked about grief, heartbreak, and starting over as a single parent.
  • She has also suggested she’s not interested in getting married again anytime soon, and that her priority is her children and her own well-being.

So in simple terms: they had a high-profile relationship, a very difficult and expensive split with legal fallout, and then a tragic ending with his cancer battle and death, which she’s navigated while trying to keep things as gentle as possible for their kids.
