Kelley Mack’s death confirmed.
Kelley Mack, a rising star best known for her role on The Walking Dead, has died at just 33 years old.
Kelley’s early life highlighted.
Born in Ohio, Mack started acting in commercials as a kid, already eyeing the screen before she hit double digits.
Her debut in The Elephant Garden earned a Student Visionary Award at the 2008 Tribeca Film Festival.
Outside of acting, Mack dipped into producing short films — proving her creativity extended far beyond performance.
Despite moving through Hollywood circles, Mack never strayed far from her Ohio upbringing.
Mack joined The Walking Dead as “Addy” in Season 9 — initially only slated for two episodes.
“Grateful to work on five episodes,” she later said, surprised her character had staying power.
Addy’s storyline earned her a quiet cult following among fans of the hit AMC horror drama.
Her star continued to rise with appearances in Chicago Med, 9-1-1, and indie shorts.
Kelley’s diagnosis unveiled.
In October 2024, Mack started experiencing persistent lower back pain — but shrugged it off.
The night before Thanksgiving, she went to the ER where an MRI revealed an abnormal mass.
By January, doctors confirmed she had diffuse midline glioma — a rare, aggressive tumor affecting the brain and spine.
Post-surgery, Mack lost use of her right leg and most of her left, requiring a wheelchair and walker.
Despite the terrifying diagnosis, she continued sharing updates with fans on social media.
On March 26, she posted a video of herself re-learning to walk, writing, “Life has had its ups and downs, am I right?”
Fans admired her honesty and resilience as she battled through pain with visible grace.

Kathryn said Kelley made the “leap to be reunited with God,” calling her “a brave, tough SOB.”
Mack’s funeral will take place in Glendale, Ohio — where friends and fans are expected to gather.
While formal tributes from co-stars haven’t been posted yet, industry insiders are reportedly in mourning.
Fans have flooded her final posts with condolences, butterfly emojis, and heartfelt goodbyes.
Her last video post — walking up stairs with effort — left followers both hopeful and heartbroken.
She leaves behind a tight-knit family who supported her every step of the way.
Her birth name was Kelley Lynne Klebenow, but to fans, she’ll always be Addy from Hilltop.
