Trouble in the grotto!

Playboy honcho Hugh Hefner's Saturday wedding to No. 1 girlfriend and Playmate Crystal Harris has been called off.

TMZ.com broke the story yesterday, reporting that the 25-year-old blonde left the Playboy Mansion over the weekend after having a fight with the publishing mogul, 60 years her senior.

Multiple sources told TMZ that Harris hauled her stuff out of the mansion and that the wedding (Hef's third) has been axed.

Turns out, it's true with Hef confirming it (how else?) via Twitter yesterday: "The wedding is off, Crystal has had a change of heart."

According to RadarOnline.com, Crystal dumped Hef for Jordan McGraw - Dr. Phil's 25-year-old son - whom she was spotted getting cozy with at an L.A. club back in March.
