Playboy founder Hugh Hefner claims he might have slept with more than a thousand women,but says he has never cheated while married. The 86-year-old,who is currently married to 26-year-old Crystal Harris,said that "he is a happy,committed,one-woman man",reported Us magazine. "How could I possibly know? Over a thousand,I'm sure. There were chunks of my life when I was married,and when I was married I never cheated. But I made up for it when I wasn't married. You have to keep your hand in," Hefner said. He wed Harris in December last year after being engaged for 2 years. She had previously run away from the couple's wedding which was supposed to happen in June 2011. "All our friends think it's made in heaven. It's only people who don't know us,who simply see us as stereotypes in terms of age and beauty. I just feel very,very fortunate to have found her at this stage in my life. I saved the best till last," he said. Hefner was wed twice before,to Mildred Williams from 1949 to 1959,and to Kimberley Conrad from 1989 to 2010.
