American model and showgirl Holly Madison poured heartaches into her newest memoir, Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a former Playboy Bunny.

According to the memoir, life in Hugh Hefner’s hutch was far from the image portrayed on TV.

The 35-year-old former Girl Next Door star who broke up with Hefner in 2008 claimed that she was bullied in the Playboy Mansion.

She also said she was subjected to “ruthless taunting”. After moving in with Hefner and his other girlfriends, Madison lost her self-esteem.

”Prior to moving into the mansion I’d been a fairly confident person, but it didn’t take long for my self-worth to start to crumble,” the model wrote in her memoir.

She also wrote in her memoir how other girls criticized every little thing about her. ”After being identified by the other girlfriends as persona non grata, I had become the victim of their ruthless ‘mean girl-ing.’ During dinners or movie screenings, it wasn’t out of the ordinary for me to overhear their loud whispers criticizing my appearance (my hair, my face, my clothes).”

Madison named her worst enemy in the Playboy Mansion as Kendra Wilkinson who she describes as the fakest person she has ever met.

According to Holly, Kendra had a huge sense of entitlement when she lived in the Playboy Mansion.

“Kendra desperately tried to make each new Playmate who arrived at the mansion her friend — and her friend alone,” Madison wrote.

According to Perez Hilton, Holly and Kendra haven’t spoken in quite some time and have absolutely no plans to do so in the future. As such, Madison is very happy to no longer be in touch with Wilkinson.

In a later part of Holly Madison’s memoir, she wrote her lesson and realization about Hefner stating: “Hef was the manipulator, and he pitted us against each other. I realized I wasn’t treated well. 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.”
