Holly Madison is trying to move on from her days at the Playboy Mansion.
The best-selling author and former partner of Hugh Hefner spoke to ET's Katie Krause on Wednesday about her new book, The Vegas Diaries: Romance, Rolling the Dice, and the Road to Reinvention. During the interview, Madison addressed a recent sexual assault lawsuit filed against Bill Cosby by Chloe Goins, which also accuses 90-year-old Hefner of negligence and conspiracy.
In Goins' lawsuit, she claims that in 2008, the Playboy founder introduced her and a friend to Cosby, who offered the two drinks that she believes were drugged. The lawsuit goes on to claim that Hefner saw that Goins was “woozy,” and suggested she lay down in a room at the residence.
The lawsuit further goes on to accuse Cosby of sexually assaulting her later that night.
Cosby’s attorney, Monique Pressley, said her client had no comment to offer at this time.
Madison told ET that while she never saw Cosby during her time at the mansion, the alleged incidents are nevertheless troubling to hear.
"I don’t know if I feel vindicated," said Madison with regard to the lawsuit, "because it makes me feel sad to hear victims' stories and I don’t really know anything about Bill Cosby per se because I don’t know him, but, you know, it makes me feel sad to hear other stories like that."
In her previous book, a memoir titled Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny, Madison claimed that Hefner had offered her drugs while they were together.
"'Would you like a Quaalude?' Hef asked, leaning toward me with a bunch of large horse pills in his hands, held together by a crumpled tissue," Holly writes in the 2015 book, adding that she declined the drugs, which Hefner allegedly called "thigh-openers."
"Hef did not miss a beat: 'Okay, that's good,' he said, nonchalantly," Holly recalls in the memoir. "'Usually, I don't approve of drugs, but you know, in the '70s they used to call these pills thigh-openers.'"
"I don't really care about his response," Madison responded to Hefner's denial in June 2015. "I wanted to share my story to inspire other women who might be in a bad relationship to get out, or not be branded by bad decisions they've made, and take charge of their lives and move on. ... I'm definitely not rewriting history."
However, Cosby did admit in a 2005 deposition that he obtained Quaaludes to give to "young women" that he "wanted to have sex with."
Meanwhile, Madison tells ET now that she has nothing to say to Hefner at this point.
"I wouldn’t say anything," she told ET. "Usually when people move on, they don’t talk to all their exes. I just don’t think it’s appropriate."
Madison also addressed the drama between her and former housemate Kendra Wilkinson, who has also accused her of lying in the past about her time at the Playboy Mansion.
"Sometimes, there’s people from your past who try and drag you down and don’t wanna see you move on," she said. "You can’t really focus on that. You have to keep looking forward, and doing what’s right for you."
"I don’t keep a feud in my mind. I don’t keep a feud in my heart," she added. "I’ve moved on so."
