Hugh Hefner

Keith Hefner - the brother of Playboy founder Hugh Hefner and frequent co-star on the reality series The Girls Next Door - has passed away at the age of 87.

Earlier this week, Playboy announced that it will cease publishing nude photos in response to the fact that there are roughly 400 bajilllion hours of hardcore pornography available for free online. 

Hef and company rightly feel that heavily-airbrushed nudes of barely legal strivers and washed-up TV actresses just don't carry much appeal in a world where HD videos of people acting out your most depraved fantasies are just a Google search away.

Friday night's double shot of Kendra on Top saw K-Dubs and Hank Baskett see a sex therapist, and the model meet with her infamous ex, as well.

Holly Madison didn’t reveal every Playboy secret in her book.

The former Playboy centerfold and author is still dishing on Hugh Hefner and his magazine empire, and she's not pulling any punches. At all.

Holly Madison's Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny is the gift that keeps on giving.

As for the man she used to date, who inspired the memoir, he was the punishment that kept on taking. Her decency, respect and emotions.

Former Playboy model Izabella St. James is weighing in on Holly Madison and why she is opening up about being Hugh Hefner's girlfriend now.

St. James' abridged theory: Holly's a pathetic, creepy, weirdo liar who's just bitter because she was the one who had to please Hefner sexually.

Kendra Wilkinson has fired a new salvo in her escalating war of words with Holly Madison, calling her former co-star irrelevant and laughable.

Holly Madison's memoir, Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny, has gotten a ton of attention.

Why is she coming out with it now, though?

If all publicity is good publicity... then Holly Madison is in the middle of a very successful book tour.

The former Playboy centerfold, who hadn't really been heard from in years up until now, is back in the news big time as she goes around talking about her new memoir.

Holly Madison no longer talks to Hugh Hefner anymore, but she sure is spilling the beans about him in her new memoir Down the Rabbit Hole.

According to Holly, he opened up since their breakup, too - in the form of creepy, uncalled-for letters long after she left the Playboy Mansion.

Kendra Wilkinson has taken a break from pretending to be angry on Marriage Boot Camp in order to actually be angry at Holly Madison.

The latter has been making the media rounds of late promoting of her new memoir, recounting her supposedly miserable life at the Playboy Mansion.

Over the past few weeks, Holly Madison has been promoting her new book, Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny.

In doing so she's shared some seriously unflattering stories about her former boss and boyfriend, Hugh Hefner.

Holly Madison is hoping to serve as a cautionary tale to other insecure, large-breasted blondes.

The former Playmate is on a promotional tour for her memoir (“Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny”) and told E! News how she responds when potential Playmates ask her for advice.

Holly Madison's new memoir does not hold back against Hugh Hefner, the aging Playboy mogul she famously dated and lived with for years.

In Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny, she puts the iconic publisher on BLAST.

In promotional material released in March for her new book, Holly Madison admits that life in the Playboy Mansion was a nightmare.

But now new excerpts from “Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny” have come out in which Madison goes into disturbing depth over just how far she fell as the girlfriend of Hugh Hefner.

Last month, we reported that Kylie Jenner may pose for Playboy once she turns 18.

Now, in a stunning turn of events, it seems the iconic men's mag has inked deals with Kylie and her older sister Kendall - both of whom will appear nude in an upcoming issue!

The Playboy Mansion has long been the celebrity world's epicenter of debauchery, with several decades' worth of wild parties at which the biggest stars of the era would shed their inhibitions (and sometimes their clothes) for some confidential grotto shenanigans.

Hugh Hefner will turn 89 next month and these days, the Mansion hosts more movie screenings than orgies, but in its '70s and '80s heyday, Hef's place was the favorite palace of sin for Hollywood's top male A-listers, some of whom had a hard time leaving...
