Holly: No Longer Hef's 'Girl Next Door'!

"I'm just kind of sad about my breakup with Hef," Holly admits. "I wish he would have seen it coming. Everybody was surprised when it happened because even though I was unhappy for a long time, the split happened suddenly... The signs were there. I was depressed for awhile."

So why did Holly and Hef split after seven years? "I want to be with somebody I can have more of a future with eventually," the "Girl Next Door" reveals. "Hef and I can't get married and have kids... so it was fun while it lasted but it wasn't right for my old age. I got too old for Hef."

Even though their relationship is on the outs, Madison told "Extra" that she's still living at the mansion! "I've been staying in the guest room -- Hef was kind enough not to kick me out of the house," said Holly, "but my condo should be ready soon."

Holly and Hef don't have a romantic future together, but where does that leave the two in terms of their business relationship? "I still work for him," said Madison. "We're still best friends. I still call and check in on him almost every day."

Madison also put in her two cents about reports the magazine mogul is dating 19-year-old twins Karissa and Kristina Shannon. "He does not waste any time, but I'm happy for him. I want him to be busy and happy and having fun." She adds, "It might be refreshing to date someone who is not high maintenance. Sorry, Hef, you know you're high maintenance. I love you but you know you're high maintenance."
