Former Playboy bunny and reality series star, Holly Madison is talking all about her life and apparently hating Kendra Wilkinson in her tell-all memoir, 'Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny'.

Apparently, Madison channeled all her anger towards her former co-star in the E! series 'Girls Next Door' where at that time, the two and Bridget Marquardt all dated the famous Hugh Hefner at the same time. During that time, the three girls seemed to be getting along just fine when all of a sudden, rumors went out saying that Madison and Wilkinson were not on good terms.

Madison opened up about their fight in her memoir writing, "Despite my attempts to befriend Kendra, she continued to push me away," Madson wrote. "Hungry from her own 'team,' Kendra desperately tried to make each new Playmate who arrived at the mansion her friend-and her friend alone."

Madison continued explaining how their situation came about. "At 19 years old, Kendra was stuck with a 9:00 pm curfew, a 78-year-old boyfriend, and a stricter set of rules than she had ever had at home," she wrote of Wilkinson when she moved in at the Playboy mansion in 2004. "And now, adding insult to injury, she was finally realizing that she wasn't as special as Hef made her believe. She was just another blond girlfriend-and life at the mansion wasn't all she imagined it to be."

Madison explains further that Wilkinson was apparently stretching the truth about their situation at the mansion and was trying to make it seem like Hefner gave more special attention to her and therefore having the impression that she was better than Madison or any of the other girls in the mansion.

"Kendra had apparently given an interview to a tabloid explaining that she wasn't friends with either of us [herself and Bridget Marquardt, Hef's third girlfriend at the time] as if she were somehow better than everyone else..." she continues, "Of course I wasn't going to stoop to her level and address this only on social media, so I decided to text her how I truly felt: that she was a coward and that she tried to act like the 'real' girl on TV, but she's the fakest person I've ever met-and that if she had a problem with me, she should have confronted me like an adult instead of just going silent."

So it may seem like the two former reality co-stars are now also former friends. "After that, I deleted her number from my phone. Kendra and I haven't spoken since, and I have to say, I don't miss her," Madison wrote.
