The former “Girls Next Door” have taken sides. At least, Kendra Wilkinson has. After Holly Madison claimed she was “miserable” during her time at the Playboy mansion with Hugh Hefner in her memoir, “Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny,” Wilkinson called her bluff. She just wanted revenge, the “Kendra On Top” star told People magazine in an exclusive interview Tuesday.

"How could [Holly] want kids and [to] get married to him and then, next thing you know, say these types of things about Hef? It's just out of revenge, and I feel bad for Hef. But you know what? He's an amazing human being,” Wilkinson, 30, said. On the E! reality show “Girls Next Door,” getting married and having children with Hefner, 89, was always in Madison’s plan.

Wilkinson mused maybe Madison, now 35, was unhappy because she felt she couldn’t be herself in the mansion. "My perception was that she acted like a First Lady," the former Playboy bunny said. "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.'”

Wilkinson said she chose to live in the famed mansion because she wanted to “have a good time.” Now that Madison has slammed Hefner, she thinks Madison’s ulterior motive -- revenge -- is “clear as day.”

In an official statement, Hefner said some people simply want to stay relevant and “rewrite history." Though he didn’t name Madison directly, it seems evident he directed the message at the release of her memoir.

“Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny” hit bookshelves Tuesday. She thanked her fans who attended the book signing in a Twitter post.
