Robert De Niro has revealed that his dad was gay reports The New York Post.



The actor, whose parents divorced when he was 3, says in a soon-to-air HBO documentary that he knew as a young man that artist Robert De Niro Sr. was gay.



He also tells Out magazine, “I wish we had spoken about it much more. My mother didn’t want to talk about things in general.”



He says it was his duty to talk about his dad’s life.



“I felt obligated. It was my responsibility to make a documentary about him,” he said.

De Niro Sr. died in 1993.
