For more than six decades, Playboy Magazine and its related content has been the landmark of the adult entertainment industry, and that's meant that Hugh Hefner's net worth has increased importantly throughout the decades - even when he's "defamed" by others that were once near him.

Hefner, a playboy on his own account regardless of his adult empire, is famous for having had several girlfriends, mostly Bunnies, at the same time, and three of them were featured in the reality show "Girls Next Door" from 2005 to 2010, as Hugh Hefner's net worth increased further from the venture and Holly Madison, Bridget Marquadt and Kendra Wilkinson turned into stars from it.

Hugh Hefner's net worth wasn't the only one increasing from the reality show, as the show featuring the Playboy Enterprises chief creative officer ended up creating a few spin-off reality shows, namely "Kendra" starring Wilkinson, "Bridget's Sexiest Beaches" with Marquadt and "Holly's World," focused on Madison.

Now, as it has been vastly published in the past few days, Madison has written a tell-all book about her years as Hefner's main girlfriend and, while her words might not damage Hugh Hefner's net worth, they could possibly add some drama to his household, as he's been married to another playmate, Crystal Harris, since 2012.

As it has been previously reported, Madison's book, "Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny," tells different tales of emotional abuse from the time she lived at the famous Playboy Mansion, but the Playboy founder has said, regardless of Hugh Hefner's net worth, that she's just twisting the truth to extend her time in headlines.

"Over the course of my life I've had more than my fair share of romantic relationships with wonderful women," Hefner told Us Weekly. "Many moved on to live happy, healthy, and productive lives, and I'm pleased to say remain dear friends today. Sadly, there are a few who have chosen to rewrite history in an attempt to stay in the spotlight. I guess, as the old saying goes: You can't win 'em all!"

Currently, Hugh Hefner's net worth stands at $50 million, according to Celebrity Net Worth, with no sign of it decreasing due to Madison's revelations.
