Legendary actor Clark Gable was secretly bisexual, according to a new biography. David Bret's book Clark Gable: Tormented Star claims the legendary womaniser had relationships with openly gay men and was "gay for pay" in his early career. It adds that, as a child, Gable was branded a "sissy" by his father, which prompted him to adopt a macho image and denounce homosexuality. The five-times-married star died in 1960 at the age of 59.
