It may not be over for DANNY DEVITO and RHEA PERLMAN.   "Extra" asked Danny if he's adjusting to being single, and he said, "It's not something you adjust to . . . Rhea and I are really close.  Actually, still together, just separate, but together."

Then "Extra" asked him if there's a chance they'll get back together.  He said, "We're working on it."
