The third time was anything but a charm for Hugh Hefner, whose wedding to Crystal Harris has been called off. "The wedding is off," Hefner glumly told his Twitter followers Tuesday. "Crystal has had a change of heart." According to TMZ, the 25-year-old model left the Playboy Mansion over the weekend after having a fight with the publishing mogul, 60 years her senior.

Multiple sources told the site that Harris moved her things out of the mansion and that the wedding, set for Saturday June 18, was canceled. It would have been Hefner's third marriage.
