It was late summer 2025 when the news hit. Most people were busy scrolling through TikTok or checking the weather, and then the headlines started popping up. Brandon Blackstock, the man who was married to Kelly Clarkson for nearly a decade, had passed away. He was only 48.
Honestly, it felt like a shock to the system for fans who had followed their very public, very messy divorce. But while the legal battles over Montana ranches and management fees were loud, Brandon’s final fight was incredibly quiet. He’d been dealing with something heavy behind the scenes for a long time.
Kelly Clarkson Ex Husband Cause of Death: The Reality
Basically, Brandon Blackstock died from melanoma.
It wasn't a sudden accident or a heart issue like some of the early internet rumors suggested. According to the Silver Bow County Coroner, Dan Hollis, Brandon passed away peacefully at his home in Butte, Montana, on August 7, 2025. He was under hospice care at the time, surrounded by his family.
Melanoma is a beast. It’s the most aggressive form of skin cancer because of how fast it can spread to other organs if it isn't caught early. Brandon had been fighting it privately for more than three years.
A Secret Three-Year Battle
You’ve gotta realize the timeline here. If he was fighting cancer for three years before August 2025, that means he was diagnosed sometime in 2022. That’s right around the time his divorce from Kelly was being finalized. Imagine dealing with one of the most publicized breakups in Hollywood while simultaneously finding out you have a life-threatening illness.

He chose to keep it out of the press. Most of us had no clue.
The first real sign that something was wrong came just a day before he died. Kelly suddenly postponed her Las Vegas residency dates for the rest of August. She posted a note on Instagram saying, "this past year, my children's father has been ill and at this moment, I need to be fully present for them."
She didn't name the illness. She didn't give details. She just shut everything down to be there for River and Remington.
Why Melanoma Is So Dangerous
We often think of skin cancer as something you just "get removed" at the dermatologist. But melanoma is different. It starts in the melanocytes—the cells that give your skin color.
If it's caught at Stage 0 or Stage 1, the survival rate is nearly 100%. But Brandon’s battle lasted years, suggesting it may have progressed or returned in a more aggressive form. Once it metastasizes (spreads through the bloodstream or lymphatic system), it becomes much harder to treat.

Experts from the American Society of Clinical Oncology (ASCO) note that while treatments like immunotherapy have come a long way, advanced melanoma is still incredibly formidable. For Brandon, who moved back to his ranch in Montana to live out his final years, the focus eventually shifted from treatment to comfort.
The Impact on the Family
It’s been about five months now since he passed, and Kelly is finally starting to open up a little bit about how the kids are doing. It's heartbreaking.
During a YouTube Q&A in early 2026, Kelly mentioned that she’s been letting her kids, River (11) and Remington (9), sleep in her bed "quite a bit." She described it as her, the two kids, and two dogs all piled in together.
- River Rose: Now 11, dealing with the loss of her father at a pivotal age.
- Remington: Only 9 years old.
- The Older Kids: Brandon also had two children from his first marriage, Savannah and Seth. Savannah actually made Brandon a grandfather in 2022 when she had her son, Lake.
Even though the divorce was "messy and painful"—Kelly’s own words—she reportedly remained very protective of Brandon once she found out he was sick. Sources say she never spoke poorly of him to the kids because she didn't want them caught in the crossfire of their parents' legal drama while their dad was fighting for his life.
Navigating Grief and Moving Forward
Grief doesn't move in a straight line. Kelly recently talked with Lionel Richie about how it hits in waves. You think you're fine, and then something small triggers a memory.

Brandon was a big part of the music industry. He managed Blake Shelton. He was Reba McEntire’s stepson for a long time. His death left a huge hole in that world, but the biggest impact is clearly on those four kids.
What We Can Learn From This
If there's any "takeaway" from such a sad story, it’s probably a reminder about health and empathy.
- Check your skin. Seriously. Melanoma doesn't care how young or successful you are. A yearly check-up with a dermatologist is non-negotiable.
- Privacy matters. Brandon and Kelly showed that even in the middle of a high-profile life, some things are worth keeping private until you're ready to share.
- Kids come first. No matter how much you might dislike an ex, when things get real, showing up for the children is the only thing that matters.
Brandon's family has asked for continued privacy as they navigate life without him. For Kelly, the focus remains on her talk show, her music, and most importantly, those "cuddles" with her kids that she says are the best part of her day.
If you or someone you know is dealing with a similar diagnosis, resources like the Melanoma Research Foundation or the American Cancer Society offer support groups and the latest info on clinical trials. Taking proactive steps for skin health—like using SPF 30+ daily and monitoring new moles—remains the best defense against the disease that took Brandon Blackstock too soon.
