The entertainment world is heartbroken over the passing of Kelley Mack, the talented actress who brought the character Addy to life in The Walking Dead. Mack died on August 2, 2025, in her hometown of Cincinnati—just weeks after celebrating her 33rd birthday.
Her family revealed that she passed peacefully following a courageous battle with diffuse midline glioma, a rare and aggressive brain cancer. Even as the illness stole her mobility, Kelley never lost her spark. She openly shared her journey, inspiring others with her resilience, optimism, and deep gratitude for the love surrounding her.
A Cincinnati native, Mack studied cinematography at Chapman University before moving to Los Angeles to pursue acting. Her career highlights include roles in Chicago Med and 9-1-1, as well as behind-the-scenes contributions to the Oscar-winning Spider-Man: Into the Spider-Verse.
She leaves behind her devoted family and longtime boyfriend. A remembrance service will be held August 16 in Ohio, followed by a celebration of her life in Los Angeles.
In a heartbreaking turn for the entertainment world, two beloved actresses have died within just 24 hours of each other.
On August 2, The Walking Dead star Kelley Mack passed away in Cincinnati at only 33, following a courageous battle with a rare brain cancer. Just one day later, on August 3, Loni Anderson—the iconic WKRP in Cincinnati star—died in Los Angeles at age 79.
Anderson, forever remembered for her witty and glamorous portrayal of Jennifer Marlowe, became a television and film favorite for decades. She is survived by her husband, Bob Flick, along with her children and grandchildren.
Though from different eras of Hollywood, both women captivated audiences with their talent, charm, and presence. Their legacies will continue to inspire, and their absence will be deeply felt.
