CRYSTAL HARRIS SET THE RECORD STRAIGHT - HEF'S LIFESTYLE WAS THE REAL DEAL BREAKER: HUGH HEFNER'S former fiancee, CRYSTAL HARRIS, went on RYAN SEACREST'S L.A. radio show yesterday to set the record straight about her break-up with Hef.

The 25-year-old says she called off their wedding -- not over money or a nasty fight -- but because the Playboy founder's lifestyle wasn't her cup thing ...

She also insisted the split was "mutual between Hef and I. There was no fight, we sat down and we talked about it."

As for those rumors about DR. PHIL'S son? Denied ...

Crystal said, quote, "I'm not seeing someone else. Of course I have friends, I have plenty of friends in the music business, so you know, that's normal." She also addressed the cover of the July issue of "Playboy", in which she sits (sans undies) in a leather chair with their dog, Charlie, holding a pipe and wearing a captain's hat and the headline “America's Princess: Introducing Mrs. Crystal Hefner" ...

She said, quote, "It's a beautiful cover and it went to print awhile ago, so I hope that people can enjoy it."
