Hugh Hefner's son, Cooper took to Twitter on Tuesday, June 23, to defend his father and slam Holly Madison and her recently released tell-all book "Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny," Us Weekly reports.

Cooper described the former Playboy bunny as a "gold digger" and accused her of falsely portraying herself in the book.

Check out Cooper's tweets below.

Us Weekly reports that in her memoir, Madison recalls her days living at the Playboy mansion and accuses Hugh of manipulating her, emotionally and verbally abusing her, and offering her drugs.

During a recent interview with Us Weekly, Madison explained that she wrote the memoir as her way of refusing to be manipulated and silenced by Hugh.

"I realized I wasn't treated well," Madison told Us. "I'm done being afraid of people. I don't have any loyalty to Hef. I haven't talked to him in four years, so there's no reason to reach out now. Besides, it's the truth."

But despite Madison's recounts of what happened at the Playboy mansion, Hugh Hefner insists that Madison's accusations are made up.

"Over the course of my life I've had more than my fair share of romantic relationships with wonderful women," Hugh explained to Us. "Sadly, there are a few who have chosen to rewrite history in an attempt to stay in the spotlight. I guess, as the old saying goes: You can't win 'em all!"

Hugh's former girlfriend Kendra Wilkinson also took to his defense and told People that Madison always had "ulterior motives" since she moving into the Playboy mansion and becoming Hugh's girlfriend.

"It's just out of revenge, and I feel bad for Hef," Wilkinson told People about Madison's memoir. "But you know what? He's an amazing human being." 

Madison has since fired back telling People that she did not write the memoir to seek revenge and all of what she wrote is true. 

"When I was at the Mansion, I got in way over my head. I thought entering into a part of his world was going to be this light, fun thing I did in my 20s," she explained, adding, "[But] I was uncomfortable with the decision I made and with the way people judged me. They still judge me now for that same situation."
