Hugh Hefner Back Together with Runaway Bride Crystal Harris

Think it’s safe to assume that Hugh Hefner isn’t one to hold a grudge? The Playboy magnate has reconciled with his former fiancee Crystal Harris.

In June 2011, Crystal — an aspiring singer — left the magazine mogul shocked when she called off their wedding just days before they were due to exchange vows. But it appears love is in the air once again after Crystal, 26, begged Hugh, 86, to forgive her.

The blonde bombshell moved back into the sprawling Playboy Mansion earlier this week. And it didn’t take long for the scoop to spread like wildfire. A spywitness spilled the reunion news to Radar Online on Thursday:

“Crystal begged Hef to let her come back. He surprisingly doesn’t have any hard feelings against her, so he let her move back into the mansion. Hef and Crystal are really happy back together… Never say never where Hugh Hefner is concerned.”

“Getting back together with Crystal Harris shouldn’t be a big surprise, since I have a history of remaining close to former girlfriends,” the Playboy mogul tweeted last night as buzz built of his reunion with Crystal.

Shortly after the split, Crystal explained she knew marriage wasn’t the right step for her.

“I got cold feet. Over time I just realized it wasn’t for me, it was all happening so fast.”

The so-called runaway bride, who narrowly escaped becoming the world’s third Mrs. Hugh Hefner when she left the men’s mag owner holding the bag at their planned wedding, has long denied that an affair with Jay McGraw — the son of TV headshrinker Dr. Phil — caused the breakup.

According to Radar snoops, Hugh’s main girlfriend Shera Berchard — the lusty lovely who has been dating the octogenarian since his split from Crystal last year — is now out of the mansion. Not true, says Hef.

“Shera and my other Mansion girlfriends welcomed Crystal here at dinner on Tuesday night, before playing games together.”
