"With heavy heart, I’m sharing the news of the passing of my beloved, Michael," Lister said. "We had 18 wonderful years together with the many dogs we fostered and adopted."
"Recently, Michael was so thrilled to reconnect with his friends from the cast of Dynasty during Emma Samms' virtual event to help raise funds for Long-Covid research," she continued. "He was a beautiful and fascinating man with many talents and skills. I will miss him forever."
