Born in 1955, David Hefner ages 64 this year, but the precise date of his birth is nowhere to be found.
Chicago-native David is the second born and the eldest son of Hugh Hefner from his first marriage to Mildred William, the Northwestern University grad.
Bearing striking resemblances to his father in term of polished feature, blonde locks and athletic built, Mr. David always stayed away from Hugh high-end and Casanova life.
