Holly Madison and Kendra Wilkinson's feud has escalated. According to a report from People, the former "Girls Next Door" stars exchanged accusations about the time they lived with Playboy founder Hugh Hefner.

After the wife of Hank Baskett slammed the tell-all book "Down the Rabbit Hole," Holly Madison in turn dissed Kendra Wilkinson for accusing her of lying about her revelations regarding the 89-year-old pornography mogul.

"I'm definitely not rewriting history," she said.

"Everything in the book is 100 percent true. I just think it's not the version of the story [Hugh Hefner] would like to tell."

"When he was approving everything that went into the TV show, it was always very happy and fun. ... He wanted things seen a certain way," she added.

Holly Madison was also accused by Kendra Wilkinson of "acting like a First Lady" at the Playboy mansion. The "Kendra on Top" star even said her ex-friend "had this ulterior motive every minute."

"I actually do take it as a compliment," Holly Madison replied to Kendra Wilkinson's diss.

"When I was at the Mansion, I got in way over my head. I thought entering into a part of his world was going to be this light, fun thing I did in my 20s. ... [But] I was uncomfortable with the decision I made and with the way people judged me."

"They still judge me now for that same situation," she added.

Holly Madison was also accused by Kendra Wilkinson of just seeking revenge because she always wanted Hugh Hefner to marry her. The married mother-of-one denied this accusation.

"It's definitely not revenge," said Holly Madison.

"If I was bitter about not having been married and wanted revenge, I would have done it a long time ago."

"I left anyway because the relationship just wan't what I wanted it to be," she explained about her past relationship with Hugh Hefner.
