Holly Madison reveals in her new memoir Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny that she hasn’t spoken to Kendra Wilkinson since an explosive feud separated them for good.

The 35-year-old former girlfriend of Playboy magnate Hugh Hefner lived with Wilkinson and appeared with her on The Girls Next Door, the E! show that gave a glimpse into the world of Hefner’s girlfriends – and turned them into household names.

But Madison tells how she was left “hurt and confused” after Wilkinson claimed she was no longer friends with either Madison or fellow girlfriend Bridget Marquardt in an interview after leaving the Playboy Mansion.

“For someone who was all of a sudden trying to act like she was better than Bridget and me, she sure wasn’t above using us for publicity when she needed it,” Madison says.

She decided to text Wilkinson and tell her she was a coward and the “fakest person” she had ever met, only for Wilkinson to reply: “WHO ARE YOU???? I DON’T EVEN KNOW YOU! WE WERE NEVER FRIENDS. IT WAS ALL JUST WORK.”

In her new book, Madison writes: “After that, I deleted her number from my phone. Kendra and I haven’t spoken since, and I have to say, I don’t miss her.”

Madison first met Wilkinson in 2004, and as soon as she was asked to move into the mansion, Wilkinson asked for the “really big room,” Madison says.

She tells how she envied Wilkinson’s “sense of entitlement,” saying she seemed to have a “hustler mentality.”

Indeed, Madison reveals how Wilkinson told Hefner how she was a college student because he didn’t like strippers.

“Here was a rookie who had just gone all the way with an old dude and her only concern was how big her room was going to be,” Madison says.

Madison described her fellow Playmate as looking “platinum and plastic” when she first met her as a 19-year-old painted lady at Hefner’s 78th birthday party.

Quite taken by the former stripper from San Diego, Hefner soon invited Wilkinson to move into the Mansion.

But Madison recalls her room was soon turned into a “jump-dump of possessions” and reeked so badly of dog urine she could smell it down the hall.

Despite her bid to befriend Wilkinson, Madison – then Hefner’s No. 1 girlfriend – said she continued to push her away.

Instead, Wilkinson tried to make friends with all the new Playmates who arrived, but banned them from being friends with her, and also Marquardt, Madison claims.

“And as it is true with any caged animal, it was dangerous when Kendra grew bored,” she writes, “I’m locked down,” she would frequently say, referring to her new life behind the gates.

“At 19 years old, Kendra was stuck with a 9 p.m. curfew, a 78-year-old boyfriend and stricter rules than she had ever had at home … she was just another blonde girlfriend – and life at the mansion wasn’t all she imagined it to be.”

Down the Rabbit Hole is out June 23.
