Holly Madison's book was dissed again by her ex-housemate Kendra Wilkinson. According to a report from Us Weekly, the former Playboy Playmate slammed the "Down the Rabbit Hole" author for being ungrateful.

"Down the Rabbit Hole: Curious Adventures And Cautionary Tales of a Former Playboy Bunny" was released by Holly Madison earlier this summer. The explosive tell-all detailed her seven-year stay inside the Playboy mansion, where she was one of the revolving girlfriends of the magazine's founder, Hugh Hefner.

Holly Madison's book narrated how the now 89-year-old pornography mogul was allegedly very manipulative and consented drug use and bullying that took place inside the Playboy mansion.

The details given by Holly Madison in her book contrasted what was shown in their hit reality series "Girls Next Door."

The show featured her life inside the infamous house, where she stayed along with other Playboy Playmates.

One of her co-stars in "Girls Next Door," Kendra Wilkinson, has repeatedly said that Holly Madison lied throughout her book. She also accused her ex-housemate of wanting to get back at Hugh Hefner for not marrying her.

''It's a shame that someone can't be appreciative of what something like that has given them," Kendra Wilkinson said about Holly Madison and the book.

Hollywood Life also reported about Kendra Wilkinson's new statements. The mother-of-two pointed out that what was shown in "Girls Next Door" simply proves that the alleged revelations that Holly Madison wrote in her book are all untrue.

''I just think it's up to people what they believe," Kendra Wilkinson said.

"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."

"I can't dictate. I can't manipulate anybody's minds,'' she added.

In Touch Weekly previously reported how Holly Madison shut down allegations that her book is meant to get back at Hugh Hefner, who has long been credited for all her career opportunities.

"I don't really care," Holly Madison said about her critics.

"I didn't write the book to get a reaction. I wanted to share my story with the people I thought could benefit from it."
