Hugh Hefner’s sons, Marston and Cooper Hefner, no doubt are caught in the middle of the impending divorce between their father and mother, former Playboy playmate Kimberly Conrad. Or are they? Read more about the story below.

Marston, 19, and Cooper, 18, are now listening to reports that their mother allegedly cheated on Hef “early in the relationship”.

The elder Hefner spoke with TMZ and revealed that he knows who the other man is, but is not making that information public. Hef claims that he remained faithful to Kimberly while they were together.

It was Kimberly’s request to stay legally married even after they separated in 1998, for the sake of Marston and Cooper, who were 7 and 8 at the time.

Hugh Hefner’s sons were featured in the January 2009 issue of Playboy magazine and poked fun of their father’s skills, or lack thereof, on the dance floor. Marston said:

“He is cool out there because his moves are so uncool. He’s a disco inferno from another planet!”

The boys don’t seem to see eye to eye when it comes to dating multiple women at the same time, much like their father does. Marston has no interest in doing so while Cooper is a chip off the old block, saying, “I don’t think it’s an odd thing to do. You date around to try to find a connection with some girl.”

While the boys may one day take over the Playboy empire, Cooper revealed his own vision:

“If I were to take over the company or have a say in what’s going on, I’d want the girls to be presented more as they were in the pictorials back in the 1950s and 1960s -— kind of artsy, classy. I would like to bring back that retro-class feel.”
