Playboy mogul Hugh Hefner and Crystal Harris could be headed down the aisle after all following their planned wedding in 2011 that was canceled days before it was scheduled to take place.
Hefner, 86, and Harris, 26, have gotten engaged again and are planning a New Year's eve wedding, a Playboy source confirms to E! News.
Harris -- who called off her wedding in June 2011 just five days before the ceremony -- has recently posted several messages to her Twitter indicating her happiness living with Hefner in the Playboy Mansion. A rep for Hefner had no official comment for ET.
In a post on Sunday, she tweeted a photo of her hand showing off a sapphire ring, with the caption, "New ring (not that kind of ring) topaz and diamonds #love #fashion." In another recent tweet, she said, "Dear past, thank you for all the lessons. Dear future, I'm ready"
