Kelley Mack, best known for her role as Addy in the hit zombie drama 'The Walking Dead,' has tragically passed away at the age of 33 after a battle with cancer. The news of her passing has sent shockwaves through the entertainment industry and among her devoted fans.
The announcement was made via an emotional post on her official Instagram page. The post read: "It is with indelible sadness that we are announcing the passing of our dear Kelley. Such a bright, fervent light has transitioned to the beyond, where we all eventually must go. Kelley passed peacefully on Saturday evening with her loving mother, Kristen, and steadfast aunt Karen present. Kelley has already come to many of her loved ones in the form of various butterflies. She will be missed by so many to depths that words cannot express."
Mack publicly revealed her diagnosis of a rare form of cancer, diffuse midline glioma, in September of last year. She had been undergoing aggressive treatment since then. Diffuse midline glioma is an extremely rare type of astrocytoma cancer.
Beyond 'The Walking Dead,' where she appeared in five episodes during season nine (2018-2019), Mack also showcased her talent in other television shows such as '9-1-1' and 'Chicago Med.' She also had a role in the TV film 'Mr. Manhattan'. In 2021, she appeared in the horror film 'Broadcast Signal Intrusion' alongside Harry Shum Jr. and Chris Sullivan.
Earlier this year, Mack starred in the comedy-drama movie 'Universal' alongside Joe Thomas (known from 'The Inbetweeners') and Rosa Robson ('Buffering').
Fans and colleagues have expressed their grief and shared tributes online, remembering Mack for her talent, kindness, and the light she brought to the screen. Her brother is fellow actor Parker Mack, known for his roles in 'Ouija: Origin of Evil', 'Faking It' and 'Divergent'. Kelley had previously shared updates on her cancer journey, including completing proton radiation treatment and undergoing physical therapy earlier this year.
Her passing is a significant loss to the acting community and a reminder of the fragility of life. She will be remembered for her contributions to the entertainment world and the impact she had on those who knew her.
