The world of entertainment is mourning the loss of Kelley Mack, an actress who faced a difficult health battle with remarkable grace.
Known to many as Addy from The Walking Dead, Mack passed away at 33 after fighting a rare and aggressive form of brain cancer. She spent her final moments surrounded by family in her hometown of Cincinnati on Saturday.
Her family shared the news with a poignant tribute on Instagram, honoring the life of a woman they called “a bright, fervent light.”
The post praised her spirit and courage in the face of her diagnosis with central nervous system glioma.
Kelley Mack’s career was marked by her versatility.
From her early days as a child actress in commercials to her celebrated voice-over work—like providing a voice match for Gwen Stacy in Spider-Man: Into the Spider-Verse—she brought a unique energy to every project.
Her film debut, The Elephant Garden, earned her an acting award from the Tisch School of the Arts, and she also produced her own short films, showcasing a talent that extended beyond acting. Fans may also remember her from guest appearances on shows like Chicago Med.
Kelley leaves behind her parents, Kristen and Lindsay Klebenow; her sister Kathryn; her brother Parker; her grandparents; and her boyfriend, Logan Lanier.
A memorial service is scheduled for August 16 in Ohio, with a second event in Los Angeles to celebrate her life. The outpouring of love and support from her colleagues and fans is a testament to the impact she had, both on and off-screen.
