Former Playboy Bunny Holly Madison is firing back after taking criticism for her new book, which describes her life in Hug Hefner's Playboy Mansion in Los Angeles. Critics of the candid memoir, titled “Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny,” have included former Bunny Kendra Wilkinson as well as Hefner himself, the Playboy magazine honcho.

In an exclusive interview with E! News on Thursday, Madison addressed Wilkinson’s assertion that Madison wrote the book as an act of revenge. "I don't know what she has against me," Madison said of Wilkinson. "I think she's just still very much a part of the Playboy fold and she didn't experience exactly what I experienced when I was there. At the end of the day, I wish her the best."

Madison also assured E! that her account of her first sexual encounter with Hefner -- an experience shared with other Bunnies -- was accurate, and suggested that some of the other women who participated may now be embarrassed that the event happened, now that they've moved on with their lives and started families. Madison also told People Now that she’s “not rewriting history” and everything in the book is “100 percent true.” The former “Holly’s World” star also revealed that Hefner frequently vetoed everything that was shown on the Playboy model's TV show, saying, “It was always very happy and fun. … He wanted things seen a certain way."

Madison dumped Hefner and left the Playboy Mansion in late 2008. She claims that Hefner continued sending her “reprimanding” letters long afterward. In an Us Weekly interview, Madison said she used to receive very formal and brief letters from Hefner, usually in response to something that Madison said to reporters. She eventually stopped opening the letters and even started throwing away the missives without reading them. “There was a very creepy vibe to them. I felt like he was trying to act like he was my dad and, like, control every move that I made," Madison said.

Despite all the backlash, Madison said she is proud to have shared her story and even plans to tell her 2-year-old daughter Rainbow about it one day.
