Cooper Hefner -- I Don't Wanna Know Who My Dad Banged (VIDEO)

EXCLUSIVE

Hugh Hefner's son Cooper doesn't know how many people his dad slept with, and he has no interest in finding out.

Cooper was having fun at Bootsy Bellows Friday night in WeHo when our photog asked him to guesstimate the number, and whether it compares to Wilt Chamberlain's self-proclaimed tally.

Fun video.
