The 85-year-old Hefner says in a Tuesday message on Chicago-based Playboy's official Twitter feed that 24-year-old Crystal Harris has "had a change of heart."
Hefner announced in December that he and the former Playmate were getting married, tweeting that he'd given Harris an engagement ring. He has said that the wedding was scheduled for this Saturday at the Playboy Mansion in the Holmby Hills neighborhood of Los Angeles.
The marriage would have been Hefner's third. He divorced Playmate Kimberly Conrad in 2009.
