Hugh Hefner May Want More Kids ... With Playboy Playmate and 'Girl Next Door' Holly Madison

Hugh Hefner is considering becoming a father again ... at age 80.

"I wouldn't say that there's a plan, but there has certainly been a conversation," the founder of the Playboy empire told The New York Daily News.

And not only is Hef considering having children with 27-year-old Holly Madison, known to viewers of his E! reality show "The Girls Next Door" as his No. 1 gal among No. 2 and No. 3 gals Kendra Wilkinson and Bridget Marquardt — he thinks she's, at last, "the one."

"This is the one," he said of Madison. "It's fascinating — I mean, with all the years and the romantic adventures and the marriages, etc. — to find something as special as this at this stage in my life is a miracle."

"This is the one with the future," he continued. "And this was not planned as a plot line — a variation on HBO's [polygamy drama] 'Big Love.' This was a unique relationship, and then the television show came along. We're just having a lot of fun with it, and life has never been better."

Madison has spoken openly about wanting to have a baby with Hefner.

"I think ‘probability' is probably an overstatement," Hefner told the Daily News, "but ‘possibility' is very real. It began as a wish, and now it's becoming, I mean, on Holly's part, it's a more serious conversation."

Hefner already has four children from two marriages, including 54-year-old Christie Hefner, who's chairman and CEO of Playboy Enterprises.

Hefner started dating again in 1998, when he separated from second wife Kimberley Conrad Hefner.

"I came out of it emotionally beat up and bruised," he told the Daily News.

Hugh's relationships after his separation included actress Brande Roderick and Chicago twins Sandy and Mandy Bentley.

"I was dating Sandy, Mandy and Brande," he told the Daily News, "which is like bad fiction."

There were still other women for Hef ... and then Madison came into his life.

"I cut back a little," he told the News. "I thinned the herd."
