Hugh Hefner calls bride-to-be who ditched him a liar and insists they had sex once a week

Crystal Harris publicly humiliated ex-boyfriend Hugh Hefner, and now Hef is fighting back. Although his retaliation is a wild overshare, the 85-year-old Playboy founder got his manhood back, at least, by telling The Hollywood Reporter that he and Harris 'had sex once a week.'The 25-year-old blonde famously told Howard Stern back in July that she and her former fiancé only had sex once and that it lasted 'like two seconds.'

Caught in the Act!

With a June wedding on the horizon, Hugh Hefner and fiancée Crystal Harris huddled close all night at the Playboy Golf Lingerie and Pajama Party at the Playboy Mansion in L.A. The two "looked smitten," according to a source at the soiree, where the soon-to-be 85-year-old also received a life-sized birthday card from Playboy Golf CEO Ajay Pathak and a bevy of Playmates.

Playboy founder Hugh Hefner to wed at 83

Playboy magazine owner Hugh Hefner is considering getting married.

The 83-year-old porn moghul admits he is happier than ever with 23-year-old girlfriend Crystal Harris and hasn't ruled out making their union official, reports gossipblender.com.

When asked about whether he would consider marriage, he said: "It's certainly possible. I certainly care enough for her. I certainly love her enough. We'll see. All I want is for the relationship to be as happy as it is. I'm having more fun than I did when I was 20."

Rumours are rife that the media mogul, who has been married three times, has had change of heart as he previously vowed never to tie the knot again.

"I haven't had a lot of luck with marriage. I don't have a good track record and I don't want to screw this one up," he had said.

Hefner first started dating Harris a year-and-a-half ago, while he was still in a relationship with 20-year-old twins Kristina and Karissa Shannon.

In January, he confirmed his romance with Harris was "getting more serious" and asked his other lovers to move out of the Playboy Mansion into the neighbouring Playmate House.

Crystal Harris Is a 'Keeper' Says Hef

Hugh Hefner says he stopped counting the number of girls he's been with a long time ago, but for now, he apparently only has one blonde to keep track of: Crystal Harris. The 23-year-old is the last girl standing out of his his most recent trio of girlfriends, after twins Kristina andKarissa Shannon vacated the Playboy Mansion a few months ago.

In a recent interview, Hugh gushed over his nearly 60 years younger girlfriend and went so far as to call her "a keeper," according to CNN. Hef will be 84 this year, and he's planning on celebrating a new year with a big bash in Vegas, with Harris by his side. "I will definitely not be celibate -- I will be celebrating," he said.

When asked about his relationship status, the Playboy mogul said: "I am in a very good relationship with a young lady named Crystal Harris." Maybe in his 84th year he'll give monogamy another shot. He was married for 8 years and allegedly faithful during that period, but before and after the marriage he was famously open about his multiple relationships.

"I was married for eight years and was faithful to that marriage throughout the entire eight years," Hef said. "I think if you make a commitment, you keep the commitment."

Hugh Hefner on Marrying Girlfriend: "It's Certainly Possible"

Hugh Hefner may be 60 years older than his 23-year-old girlfriend Crystal Harris, but that doesn't mean marriage for the two is totally out of the question.

Hef, who turns 84 on Friday, tells me there could be another wedding in his future…

"It's certainly possible," Hefner told me earlier today from the Playboy Mansion, where he was getting ready for his weekly game night. "I certainly care enough for her…I certainly love her enough. We'll see. All I want is for the relationship to be as happy as it is."

Hef's been with Harris for about a year and a half. The two first hooked up when the media mogul was also beginning a relationship with the Shannon twins, who have since moved out of the mansion and into the neighboring Playmate house.

The Girls Next Door poobah and Harris (along with a gaggle of Playmates, of course) are jetting to Las Vegas on Saturday night to celebrate his birthday with a 1980s-themed birthday bash at the Palms Casino Resort's Playboy Club and Moon nightclub.

"I'm having more fun than I did when I was 20," says Hefner.

He's also having fun watching longtime friend Pamela Anderson on Dancing With the Stars, but realizes she's a "long shot" to win. Believe it or not, Hefner has never been approached about competing for that discoball trophy. If they could have Buzz Aldrin on the show, why not the Playboy mogul?

"They haven't asked and I can tell you ahead of time I won't be there," he said, adding with a laugh about Aldrin, "He's a good friend, but he looked a lot cooler on the moon than he does on the dance floor."

That's not all the Hef I have for ya. Come back here tomorrow to find out what he has to say about Kendra, Jenny McCarthy and Kate Gosselin.
