The Playboy magazine mogul and his fiancee Crystal Harris have called off their wedding just days before they were set to marry.
"The wedding is off. Crystal has had a change of heart," he tweeted after reports emerged that the couple had split.
Hefner had proposed to Harris on Christmas Eve with a large diamond ring.
The proposal came only months after he finalised his divorce from his second wife, Kimberley Conrad, despite the fact both had been living apart since the late 1990s. He has two sons with Conrad.
His first marriage, to Mildred Williams, ended in 1959, six years after he founded Playboy magazine.
