Oh, tears, Hugh Hefner won't be getting married this weekend after all. "The wedding is off," he tweeted. "Crystal has had a change of heart." Crystal Harris later elaborated, "After much deep reflection and thought I have decided to end my engagement with Hef. I have the utmost respect for Hef and wish him the best going forward. I hope the media will give each of us the privacy we deserve during this time." Maybe she realized that she couldn't be married to a man who bones other people? Maybe she got the news that his first divorce went down in 1959? Or maybe, as Page Six alleges, something much more sinister happened. They claim that Crystal has been dating someone else—Jordan McGraw, aka Dr. Phil's son—for months and that her plan was to walk down the aisle, say "I can't go through with it," and ditch Hef there while Lifetime TV cameras rolled. She allegedly thought this would make her an instant media star. And Hugh's latest tweet makes me believe this tale. "Since we're not getting married on Saturday, I've scheduled a movie: 'Runaway Bride.' Seems appropriate," he typed. Poor guy. [People, NY Post, Daily Beast]

Whatever the story, Hugh and Crystal are no more. After the jump, more famous folks who called off their weddings.
