Hugh Hefner’s ex-fiancee Crystal Harris has moved back into the Playboy Mansion!

Harris infamously left Hef a week before she was to marry him and jumped into another man’s arms.

Apparently, there are no hard feelings because Hef has welcomed her back into his home and his current girlfriend has even moved out!

“Crystal begged Hef to let her come back,” a source reveals. “He surprisingly doesn’t have any hard feelings against her, so he let her move back into the Mansion.”

For those of you who don’t remember, Harris even graced the cover of Playboy the same month she ran away from Hef! He later placed a “Runaway Bride” sticker on every cover published.

“Hef and Crystal are really happy back together,” says the insider.

But not everyone is thrilled about the reunion. “Shera Berchard, Hef’s #1 girlfriend, moved out as soon as Crystal moved back in.”

Clearly moving in your ex-fiancee is going to start some drama.

Well good for them.

He’s almost 90-years-old and she needs a place to live… they’re perfect for each other.
