Vanessa Redgrave
“I am, to say the least of it, bisexual,” the British actor Michael Redgrave told his writing partner when they were working on his autobiography. In the end, they left that part out of the book. His daughter Vanessa (seen here in 1966’s “Blow Up”) has also kept quiet on the subject. But in 2011, her daughter Joely Richardson stepped forward to deny the claim in an unauthorized biography that Vanessa once walked in on her father in bed with her husband.
