Another Playmate Slams Holly Madison: 'She Had The Ability To Walk Away'

Playboy pinup Holly Madison - who dishes the dirt on Hugh Hefner in a new book - is being blasted by another former playmate over her account.

Izabella St. James, who spent two years living in the Playboy mansion with Holly, has told INSIDE EDITION that she doesn't recognize the grim picture Holly paints in her best-selling book, Down the Rabbit Hole.

“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,” Izabella said.

Holly has made claims in her book that there was "not a whole lot" going on in Hef's bedroom. She also claims she endured years of emotional abuse.

But Izabella calls Holly's book "vengeful."

Holly had a single-minded determination to be Hef's favorite, according to Izabella.

“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," she said. "Anything to endear herself to him.”

It's not the first time Holly has taken heat over her book. She's also been trading insults with Kendra Wilkinson, her former co-star in the Playboy reality TV show, The Girls Next Door.

'The one thing she truly wanted was a piece of that stock, a piece of Playboy and a piece of Hef's will,' Kendra told People in an interview earlier this month.

'She considers herself a failure because she did whatever it took to get that and she didn't get what she wanted in return.'

But Holly is getting good news too -- Down the Rabbit Hole is number one on the New York Times non-fiction list.
