Hugh Hefner’s fiancee allegedly planned to ditch the 85-year-old Playboy founder at the altar in exchange for $500,000 to give a reality special an exclusive, reports the New York Post’s Page Six.

Crystal Harris, 25, was shopping the deal to tell her side of the story in a reality special after planning to abandon Hefner at the wedding, the story says. But the pair called off the wedding before the event when they had an argument on Sunday and Harris moved out of the Playboy mansion, the piece adds.

A source quoted in the story says: "Crystal wanted to ditch Hef at the altar. Her plan was to walk up the aisle and say she couldn’t go through with it. The wedding was to be filmed for a reality special, and her refusal to marry him would be a sensation. She was looking for a tie-in deal of around $500,000 for the exclusive ‘I ditched Hef at the altar’ interview. While there was interest, Crystal didn’t get an offer anywhere near half a million."

Harris allegedly has been seeing Jordan McGraw, son of television therapist Dr. Phil McGraw, behind Hefner’s back, although it’s unclear whether her fight with Hefner was over that or another issue, the piece notes. Harris’ manager denied reports about her relationship with Jordan McGraw and said to his knowledge it wasn’t true that she was seeking a media deal, calling the split "an amicable breakup," the article adds.
