Cooper Hefner is making a preemptive strike to stick up for his famous father.
On Jan. 24, A&E will debut the docuseries, "Secrets of Playboy," which is expected to cast a very negative light on late Playboy founder Hugh Hefner and the inner workings of the Playboy Mansion.

Previews already show several of Hugh's former girlfriends, Playmates and members of the Mansion staff alleging that drugs, coercion and secret sexual recordings were a part of life in the famed home.
Just 24 hours before the first episode, Cooper, who Hugh shares with ex-wife Kimberley Conrad, tweeted, "Some may not approve of the life my Dad chose, but my father was not a liar. However unconventional, he was sincere in his approach and lived honestly. He was generous in nature and cared deeply for people."
Cooper, the former Chief Creative Officer at Playboy Enterprises, added, "These salacious stories are a case study of regret becoming revenge."
One of the voices in the series is Holly Madison, who dated the magazine magnate from 2001 to 2008.
"The reason I think the mansion was very cult-like looking back on it is because we were all kind of gaslit and expected to think of Hef as like this really good guy," she says in the series, according to E! News. "And you started to feel like, 'Oh, he's not what they say in the media, he's just a nice man.'"

Holly, who's had issues with her ex over the years, believes she developed Stockholm Syndrome during those years living under the Playboy Mansion roof.
"I felt like I was in this cycle of gross things, and I didn't know what to do," she said.
