Playboy magazine founder Hugh Hefner says his fiancee has called off their wedding.
The 85-year-old said in a 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 had given Harris an engagement ring.
He has said that the wedding was scheduled for this Saturday at the Playboy Mansion in Holmby Hills, California.
The marriage would have been Hefner's third. He divorced Playmate Kimberly Conrad in 2009.
