“With heavy heart, I’m sharing the news of the passing of my beloved, Michael,” Nader’s wife Jodi Lister said in a statement via MichaelFairmanTV.com.

“We had 18 wonderful years together with the many dogs we fostered and adopted,” said Lister. “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. He was a beautiful and fascinating man with many talents and skills. I will miss him forever.”
