Playboy's main man talks candidly.

Hugh Hefner is opening up about his emotional breakup with main girlfriend Holly Madison.

"I had planned to spend the rest of my life with Holly," the Playboy mogul told Us magazine, explaining that after their falling out, "I was road kill a couple of weeks ago."

Hef, 82, admits that he and Holly, 28, were unable to have kids, and that played a role in the split: "We tried to have a baby earlier this year and it didn't work out," he said. "She became very depressed."

Last month Hef told the mag: "She is still my girlfriend," he said. "Now will that last? I don't think anything lasts forever."
