Any hope Girls Next Door vixen Holly Madison may still have of marrying her Playboy prince, Hugh Hefner, may have finally slipped down the rabbit hole.

At the 2008 Playboy Playmate of the Year party held at the Playboy Mansion, Hefner said, "I love Holly very much and I think we're going to be together the rest of my life. But marriage isn't part of my puzzle. It's not a personal thing--I just haven't had much luck with marriages."

Hefner,82, whose life with his three girlfriends, Madison, Kendra Wilkinson and Bridget Marquardt is featured on E!'s hit reality show The Girls Next Door, often follows "main girlfriend" Madison's desire to marry the elderly tycoon.

Of Hef's refusal to tie the knot the 28-year old says, "We are no closer to getting married than we were two years ago. It's like a car stalled at the side of the road."

Meanwhile, Hefner may not be settling down anytime soon, but when it comes to retiring, he says it's not in the cards.

"I have no plans to retire," he said. "It's the perfect combination of work and play that keeps you young. If I quit work it would be the beginning of the end."
