Holly Madison and Kendra Wilkinson have had plenty to say about each other over the years, but Madison thinks enough is enough.

The former Girls Next Door stars had a falling-out several years ago, and their feud was reignited over the summer when Madison published her memoir Down the Rabbit Hole, in which she claims group sex, drug use and alcohol abuse was rampant at the Playboy Mansion. Wilkinson has slammed the memoir as rewriting history, and in a recent episode of Kendra on Top, she contemplated confronting Madison at a book signing. (The confrontation never took place.)

Madison says she’s not surprised Wilkinson hasn’t reached out to her to talk about their differences.

“She could, but I don’t think she ever would, because in my experience with her I found her to be the type of person who really likes to talk tough and act tough when the cameras are on her,” Madison tells PEOPLE. “But in reality, she’s just another passive-aggressive human, like the rest of us.”

Madison, who calls that book signing episode of KoT "a new low," says as far as she is concerned, the women’s feud is over, with both of them having had the chance to tell their stories in their own books. Wilkinson published the memoir Sliding into Home in 2010.

“I told my story about my life at the mansion and my experiences with Kendra and my experiences on the show, and she did the same thing about five years ago,” Madison says. “She said things in her book about Bridget [Marquardt] and I that weren’t true, but I didn’t go around throwing a fit about it. We’ve each had our chance to tell the story and how we interpreted certain situations.”

On the Oct. 2 episode of Kendra on Top, Madison phoned Playboy mogul Hugh Hefner to offer her support over his unflattering portrayal in Madison’s memoir.

Madison says that she and Wilkinson see their days at the Playboy Mansion very differently.

“I don’t think she has the wherewithal to really realize what that situation was about. She sees somebody who is a pop culture icon and someone who has a lot of money and she is still very blinded by that,” says Madison. “She’s the type of person who will throw me under the bus, throw her mom under the bus. But if it’s somebody rich and famous, she’ll always come back and bow down.”
