Holly Madison is living proof that the Playboy mansion is not for everyone.

Kendra Wilkinson, 30, rushed to Hugh Hefner’s defense in June following Holly’s abusive allegations against the 89-year-old in her tell-all book, "Down the Rabbit Hole."

In the memoir, the 25-year-old revealed she was depressed and even contemplated suicide during her time in the mansion, where Hef allegedly verbally abused her with derogatory language, writing "reprimanding" letters for her press comments and being offered prescription drugs.

But Kendra's putting up a fight!

"I just think it’s up to people what they believe," Kendra told Us Weekly at the Beverly Hills ABC Galaxy BabyFirst TV premiere on Saturday. "The proof is out there on The Girls Next Door. At the end of the day, people made up their minds already if they believe it or not. So I can’t dictate. I can’t manipulate anybody’s minds."

Back in June, Kendra even accused the 35-year-old of having “ulterior motives” for being with Hef.

"My perception was that she acted like a First Lady, you know, she had to play a part, play a role every day being there. Like, 'I have to be this in order to get this,'" she told People.

"Holly, you can tell, had this ulterior movie every minute being in the Mansion, and that motive was — it was clear as day — she wanted Hef's kids, she wanted a piece of Playboy and she wanted to marry Hef for, obviously, his will."
