Hef Had Family Foursome, Gay Tryst

Hugh Hefner has signed off on a new biography that delves into the Playboy kingpin's sexual liberation, the New York Post reports. In "Mr. Playboy: Hugh Hefner and the American Dream," Steven Watts writes how the skin-mag magnate had a foursome with his first wife, his brother Keith and his sister-in-law, starred in a porno, and received oral sex from a man.

"This is the most authoritative book ever written about me," Hef told the paper. "It's all essentially true."
