The October issue of Details magazine revealed Hefner reiterating that among the three blonde girlfriends he is living with, Holly Madison was the lucky woman to captivate his heart.

"I love Holly the most. Five or six years ago, she was simply one of seven girlfriends, but... I fell deeply in love with her," Hefner said.

The 81-year-old personality said that his relationship with Holly Madison is one that "will last the rest of my life," and it isn't surprising as it was reported earlier this year that the two may get married before 2007 ends.

In March, the New York Post's Page Six officially reported that Hefner was making plans of a marriage with Madison before the end of this year. The tabloid added that the wedding will be featured in The Girls Next Door. Following the reports, Hefner denied the claims, however admitted that he wanted to pursue a monogamous relationship with Madison.

Madison is pleased with the outcome of the past months, as the 27-year-old Playboy Playmate has likewise proclaimed Hugh Hefner as the love of her life. During the Monte Carlo Festival, she told a reporter that she wants to "have kids with Hef in the next year or so and when that happens I just want it to be me and him."

Hefner also told Details magazine that his other girlfriends, Bridget Marquardt and Kendra Wilkinson were not the jealous type, and were not upset about his revelation.

"They don't [get jealous]. But whether it's three girlfriends or seven, it's easier than one wife. They're not going to give you a hard time, because you always have an alternative," Hefner explained. "My second marriage, from 1989, lasted 10 years, and we had two children. When it ended I met a young actress name Brande Roderick, and about three weeks later a pair of twins, Sandy and Mandy Bentley. It was an overreaction to a difficult marriage."

The Girls Next Door has been renewed for a fourth season.
