Hugh Hefner and Crystal Harris may have called it off months ago, but it seems the drama isn't quite over. People reports that the two are locked in a custody battle over ... the pair's Cavalier King Charles spaniel. Hef says his runaway bride gave him the OK to keep Charlie, but now she apparently wants the dog back. Hef is trying to convince her that she'd be happier walking away with some other loot: "I told her if she wants to keep the ring and the Bentley, then maybe I can keep the puppy. I [hope] we will work it out." Observes Hef, "The puppy's valuable, but not $100,000 worth." (More celebrity stories.)
