Is a reconciliation on the horizon for Danny DeVito and Rhea Perlman?

In an interview with "Extra" Tuesday, DeVito revealed that he and his wife of 30 years are "working on" their marriage. When asked how he was adjusting to life as a single man , DeVito replied, It's not something you adjust to. Rhea and I are really close. Actually still together, just separate, but together.
