Playboy founder Hugh Hefner said on Tuesday his wedding this weekend has been canceled because his 25-year-old fiance, a Playmate from his magazine, changed her mind.

Hefner, 85, and Crystal Harris were due to tie the knot in front of more than 300 guests at the Playboy Mansion in Los Angeles on Saturday. It would have been Hefner's third marriage.

"The wedding is off. Crystal has had a change of heart," according to Hefner.

There were also rumors of Crystal being close buddies with Dr. Phil's son Jordan McGraw.
