Kelley Mack, born Kelley Lynne Klebenow, best known for her role as Addy in The Walking Dead Season 9, passed away on August 2, 2025, at the age of 33 in Cincinnati, Ohio. She died peacefully surrounded by her mother and aunt, following a courageous battle with a rare form of brain cancer known as diffuse midline glioma (DMG).
Initially believing she had a slipped disc due to persistent lower back pain and nerve sensitivity, Mack underwent an MRI in September 2024 that revealed the tumor pressing against her spinal cord. She was later diagnosed with DMG, an aggressive and terminal central nervous system cancer that typically affects children and young adults.
Her case highlights how serious symptoms like chronic back pain and unexplained nerve issues should never be ignored.
A Talented Career in TV and Film
Mack had over 35 acting credits and was also a producer on five projects. Her breakthrough came with The Walking Dead, but she also made notable appearances in:
Chicago Med
9-1-1
The College Tapes
Broadcast Signal Intrusion
Voice work resembling Gwen Stacy in Spider-Man: Into the Spider-Verse
Commercials for Dr Pepper and Chick-fil-A
She was admired not only for her talent but also for her warmth and sincerity in the entertainment industry.
Family's Statement and Legacy
In a heartfelt post, Kelley’s sister, Kathryn, described her as a “bright, fervent light” and expressed deep grief over her loss. A Celebration of Life event will be held on August 16, 2025, in Glendale, Ohio, where family, friends, and fans will honor her memory.
“She fought with grace and strength until the very end. Her light, talent, and kindness left an impact on everyone she met.” – Family Statement
Kelley Mack’s passing serves as a reminder of the dangers of rare diseases like DMG, which can be misdiagnosed or overlooked. Her story is a call to action: if your body is sending signals—listen.
Her impact as an actress, creator, and voice in the entertainment industry will continue to resonate with fans and peers alike.
