Hugh Hefner is finally talking about his split with head bunny Holly Madison. The Playboy mogul says he is "down in the dumps" about his break-up with Holly, and he seems to be a little shocked that Madison is talking about it to the media.

"If Holly says it's over, I guess it's over," Hefner said in a telephone interview Wednesday. "She's still here in the house. Until a few days ago, we were still sharing the same bed."

The break-up is evidently the result of Hef breaking the news to Holly that the couple won't get married or have any children.

"The fact that she was depressed after that, I didn't know at all. That was a revelation in the last days and weeks. Quite frankly, we thought when the time came, we would make a combined statement and we expected that combined statement would be somewhere in the weeks and months ahead."

As for the "Girls Next Door" on E!, Hefner says the show will go on for a sixth season.

"It's now apparent there will be some new faces in my personal life and on the show," he said.

"There's been moments that I've been down in the dumps about all this, and (personal assistant) Mary (O'Connor) told me to cheer up and pointed out that there are girls lined up outside the front gate. At my age, that's hard to believe, but it seems to be true."

Hefner admits that there will be more girlfriends, but he said he expects to maintain some sort of relationship with Holly.
