Hugh Hefner of 'Playboy' fame tweeted around 2:40 p.m. on Wednesday stating his pending nuptials to Crystal Harris are off. Hef tweeted The wedding is off. Crystal has had a change of heart.

Poor guy. This news comes just five days before the wedding was supposed to happen. Apparently, the couple had an 'explosive' argument in the Playboy Mansion, according to E! Online.

The fight allegedly took place over the phone-what caused it remains unknown-and resulted in the 25-year-old Harris abruptly packing up and moving out of the house, E! reports. 

This would have been 85-year-old Hef's third marriage.

Since Hef is back on the market, here's a look at some of his best outfits, bathrobes and otherwise.
