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"
