Holly Madison is just bitter she’s not Mrs. Hefner, Kendra Wilkinson says

Holly Madison is out for revenge, Kendra Wilsonson says, and that’s what’s behind the Hugh Hefner-bashing in Madison’s new tell-all book.

“She had this ulterior motive every minute being at the mansion ...,” Wilkinson told People Now. “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.”

Nobody got married, she said, “so what do you think’s gonna happen. Revenge. We’re witnessing some revenge here.”

Wilkinson and Madison, veterans of “The Girls Next Door,” both lived at the Playboy mansion as Hefner “girlfriends.” While the former says she’s thankful for everything Hef and “the mansion” did for her life, the latter is now telling tales out of school that paint the Playboy honcho as a pathetic figure who was a control freak, a cheapskate and really bad in bed.

In one anecdote from her book — the New York Post had an exclusive peek Sunday — Madison described her first visit to Hef’s lady-filled bedroom.

“The girlfriends, in various stages of undress, were sitting in a semicircle at the edge of the bed — some kneeling, some standing, some lying down,” she wrote. “I sat myself on the edge of the bed — unsure of what to do next. I leaned into Vicky . . . ‘Maybe if I hide behind her,’ I thought, ‘I’ll go unnoticed for the night.’”

After being told to fake it like everyone else was, Madison said, she joined in the action and had a “zero intimacy” experience with the man of the house. She regretted it the next morning — so she moved in?

“I felt stuck in my life, trying to make ends meet,” she wrote. “I lost the lease on my apartment. I felt like I’d already thrown myself to the wolves, so I might as well reap the rewards and not just be one more slut who walked through those doors.”

Hefner, meanwhile, maintained that a great many of the women he’s been romantically involved in over the years have gone on do to well and remain his friends.

“Sadly, there are a few who have chosen to rewrite history in an attempt to stay in the spotlight,” he told Us Weekly in a statement Monday. “I guess, as the old saying goes: You can’t win ‘em all!”

Madison, however, told “Entertainment Tonight” that in the book, which is out Wednesday, she was finally telling the truth about her experience.

“I fell for his act, hook, line and sinker. I really cared about him,” she explained.

That said, if he were to call her now, she wouldn’t bother to answer the phone.
