Washington, January 24 : Octogenarian `Playboy' mogul Hugh Hefner's estranged wife Kimberly Conrad recently caused quite a stir of surprise by showing up at his mansion for one of his female-frenzied movie nights.

She was seen spending the evening hanging out with a bevy of beauties and the men's magazine mogul.

That was surprising for many because she had once revealed that she would go there only for Tuesday's "Family Night", when no other hotties were hopping around.

"They still have a very special connection, you can see that when Hef looks at her," Fox News quoted a mansion insider as telling Tarts.

Conrad and Hefner married in 1989, and have two teenage sons together. They separated ten years later, but never divorced.

The insider revealed that it was not likely that they would divorce each other.

"This upset Holly (Madison) a lot, as she really did want to marry Hef and have a family with him, but she realized it was never going to happen and that's when she left," said our source.

Holly, Bridget and Kendra have officially left the Holmby Hills residence and Hefner's new squeeze Crystal Harris has bumped the troublesome twins to take Madison's spot as the number one girlfriend. (ANI)
