Hugh Hefner

Hugh Hefner gave "Extra" a personal tour of his famous residence -- the Playboy Mansion. The publisher wore his signature silk pajamas for an interview about his public breakup, his autobiography and the latest issue of the sexy mag. What is the Playboy founder's favorite part of the almost 22,000 sq. ft. home? "No question -- the bedroom. I do my best work in the bedroom."

Hefner admits he was heartbroken over his split with longtime girlfriend Holly Madison. "I was blindsided by the breakup... but Holly was looking for something more that I couldn't give her. She was looking for marriage and children." Hefner eventually moved on -- with two times the trouble. "Within two weeks, a pair of twins arrived and it turned out they were interested in being my girlfriends... Several girlfriends are easier to handle than one wife."

Hef talked about his autobiography, "Mr. Playboy," that lets readers into a life filled with luxury, women and sex. The author was not the least bit embarrassed about the book's most shocking revelation. "Probably an incident that occurred back in the late seventies where I almost swallowed a sex toy."

Sex icon Marilyn Monroe was the first to grace the cover of Playboy. This month's 55th anniversary issue features Carmen Electra. Hef has his eyes on two of Hollywood's married women for future issues. "Either Angelina Jolie or Scarlett Johansson."

Holly Madison has made it clear that she wanted to have children with ex Hugh Hefner. But did the bodacious blonde get a little help from science?

This one is true! In Touch Weekly says the "Girls Next Door" babe did everything she could to have mini Hefs of her own. She even tried fertility treatments.

Hugh Hefner may be saying sayonara to current girlfriends Holly Madison and Kendra Wilkinson -- but don't expect the Playboy mogul to live alone in an empty house.

Hef confirmed to AP that twin Playmates Karissa and Kristina Shannon, 19, have moved into the mansion, but he's not dating them -- yet. "It's now apparent there will be some new faces in my personal life and on the show," he said.

Hugh confirmed his split with Holly, saying, "If Holly says it's over, I guess it's over."

Fellow "Girl Next Door" Kendra admitted things were over between her and Hef on the Chelsea Handler show Tuesday night -- and confirmed she was now seeing pro-football player Hank Baskett.

The 82-year-old magazine publisher has been down due to the house changes -- but remains optimistic for the future. He said, "There's been moments that I've been down in the dumps about all this, and (my personal assistant) Mary told me to cheer up and pointed out that there are girls lined up outside the front gate. At my age, that's hard to believe, but it seems to be true."
