Hugh Hefner & Crystal Harris: The Wedding is Off!

The third time is apparently not always the charm, as Hugh Hefner's upcoming nuptials to Crystal Harris have been called off.

As TMZ reports, the 25-year-old model has nixed all wedding plans after a weekend argument with her 85-year-old fiancee, which prompted her to move out of the famed Playboy mansion.

Hugh and Crystal began dating back in 2009, before announcing their engagement last Christmas.

The now-canceled wedding, which was scheduled for this Saturday, June 18, would have been the third walk down the aisle for Hefner.
