Despite having previously called off their initial plans to tie the knot, Hugh Hefner and Crystal Harris are attempting another wedding, which apparently calls for another engagement ring.

To confirm the rumors of the couple's renewed plan to get hitched, Hef wrote on his Twitter page, "I've given Crystal Harris a ring. I love the girl." Crystal added to Hef's tweet by subsequently posting photos of her new engagement ring. Though both have been tight-lipped about when they will exchange vows, sources say that they intend to do so on New Year's Eve at the Playboy Mansion.
