Izabella St. James and Kendra Wilkinson have taken aim at Holly Madison.

Holly Madison Has Issued A Warning To Hugh Hefner's Wife Crystal Harris

Following the release of Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny, which has been on the New York Times' Bestsellers List for the last four weeks, Madison has faced backlash from her fellow Playboy Playmates.

"Holly is so cunning and so manipulative. I think she has chosen to portray herself as a victim and vilify key players along the way,” St. James revealed to Inside Edition on Thursday. "“She emulated Hef, she dressed like him, she studied his likes and past girlfriends that he particularly liked, their looks, the dresses they wore that he particularly liked, she would have the same ones made for herself. Anything to endear herself to him.”

Earlier this month, Wilkinson spoke to PEOPLE Magazine, calling the timing of Madison's book release questionable.

"It's pretty sad. It makes you question the timing, and it makes you wonder, 'Wow, she wants real revenge.' At the end of the day, true colors shine," Wilkinson explained.

"The one thing she truly wanted was a piece of that stock, a piece of Playboy and a piece of Hef's will," Wilkinson alleged. "She considers herself a failure because she did whatever it took to get that and she didn't get what she wanted in return. Hef is the most amazing human being. Behind the scenes, people that actually know the truth are laughing their asses off. This is not even real. This person is out for revenge."
