"It is with unimaginable heartbreak that I am sharing with you, that my beloved husband, Cliff Simon, passed away..." Colette wrote. "He was known to most of you on this page as the villain you loved to hate, Ba'al, from Stargate SG-1. But as he said, 'acting is what I do, it's only a part of who I am.'"
