Cooper, the youngest of Hefner's four children, has achieved quite a lot at age 26. He is the Chief Creative Officer at Playboy Enterprises, the founder and former CEO of upstart media company HOP, and a member of the California State Military Reserve.
Cooper's mother is Kimberly Conrad, Hefner's second wife and former Playmate of the Year. Conrad and Hefner divorced in 2010 after 11 years of separation.
Cooper confirmed his father's death with a statement to People on behalf of the company:
"My father lived an exceptional and impactful life as a media and cultural pioneer and a leading voice behind some of the most significant social and cultural movements of our time in advocating free speech, civil rights and sexual freedom. He defined a lifestyle and ethos that lie at the heart of the Playboy brand, one of the most recognizable and enduring in history. He will be greatly missed by many, including his wife Crystal, my sister Christie and my brothers David and Marston, and all of us at Playboy Enterprises."
He grew up at the Playboy mansion, and you can follow his lavish lifestyle on Instagram.
