Looking Back at the Most Important Women in Hugh Hefner's Life

Hugh Hefner passed away yesterday at 91 years old.

With a lifetime full of accomplishments, fame, friends and success, it's no surprise so many people have expressed their sadness regarding the Playboy mogul's death—especially the women he employed and worked with over the years.

However, while there were plenty of Playboy bunnies, platinum blondes and models who came in and out of Hefner's life (not to mention, the mansion), there were a select few who were just a little extra special to him.

Hefner was married three times, and though you may not agree with it, he also had several long-term partners who he considered very important women to him, even if he was dating other people at the same time.

Meanwhile, on Wednesday evening, Playboy announced that Hefner had passed away from natural causes at the Playboy Mansion. 

"My father lived an exceptional and impactful life as a media and cultural pioneer and a leading voice behind some of the most significant social and cultural movements of our time in advocating free speech, civil rights and sexual freedom," his youngest son, Cooper Hefner, shared in a statement. "He defined a lifestyle and ethos that lie at the heart of the Playboy brand, one of the most recognizable and enduring in history."

Cooper continued, "He will be greatly missed by many, including his wife Crystal, my sister Christie and my brothers David and Marston, and all of us at Playboy Enterprises."

Information regarding memorial services are not available at this time.
