Playboy founder Hugh Hefner has been called a lot of things over his 85-year lifespan - entrepreneur, gigolo, misogynist, reality TV star. Now Mr. Hefner can add "dumped days before the wedding" to his dubious distinctions. Yes, good ol' Hef tweeted last Tuesday that his marriage to Crystal Harris has been officially cancelled.

"The wedding is off," Hefner, 85, tweeted Tuesday. "Crystal has had a change of heart."

The pair was engaged last Christmas Eve, but according to reports things had recently gone sour between the two. Hefner and Harris allegedly had a massive argument last week. TMZ is reporting Crystal moved out of the infamous Playboy mansion over the weekend and called off the wedding, which was to take place on Saturday, June 18.

Crystal has remained silent over the decision not to go through with the marriage, but her tweets are giving fans of the Playboy model some insight into why she called off the nuptials.

"There are two mistakes one can make along the road to truth... not going all the way, and not starting," she said on Twitter on Tuesday.

The pair was all set to walk down the aisle in front of 300 friends and family. Guests were instructed to donate to charities in lieu of gifts for the couple and all of the ceremony details had been arranged. Back in April, Hefner toldUs Weekly that Harris had planned every aspect of the big day.

"Everything is in place," he said at the time of the wedding. "She's wonderful and she's done a really terrific job so far with all the planning. She is the one for me!"

This would have been Hefner's third marriage. He and Harris started dating in 2009 after she was named Playmate of the Year.

Poor Hugh Hefner. Being left at the altar can't be a great feeling. But look on the bright side, Hef; at least you won't have to visit a divorce lawyer in Pasadena.
