Hugh Hefner's Sons Marston & Cooper Hefner Love Classy Nude Pictorials

Meet Marston and Cooper Hefner - the sons of Playboy founder Hugh Hefner and his soon-to-be-divorced wife Kimberley Conrad.

Marston and Cooper were raised by their mother, former Playmate Conrad, in a house next door to the Playboy Mansion after their parents separated. Hefner and Conrad were married in July 1989 and separated nine years later, but remained legally wed. After an 11-year separation, Hefner finally filed for divorce this week.

Marston Hefner, an 19-year-old college student, and his 18-year-old brother Cooper said in an interview published in Playboy magazine that change is inevitable at the struggling publication.

"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,"' Cooper said.

Hef is currently dating 19-year-old twins Karissa and Kristina Shannon and Crystal Harris. But his boys can't agree on how they feel about their dad's notorious coterie of girlfriends.

"I'm not going to have multiple girlfriends - not at the same time," Marston who clearly lacks the Hefner sex gene says. "I can't imagine that."

Cooper, begs to differ. "I don't think it's an odd thing to do," he says. "You date around to try to find a connection with some girl."

His mom, he adds is "all about one girlfriend at a time."

Life as the sons of the Playboy founder has its privileges - their birthday cakes always had naked ladies inside. But one of the few negatives is the large picture of Marston and Cooper's naked mother in the mansion's library!
