Danny DeVito and Rhea Perlman -- 'We're Still Together'

Danny DeVito and Rhea Perlman are actively trying to save their marriage ... so says Danny.

DeVito revealed the status of his 30-year marriage at an event in L.A. this week -- after "Extra" correspondent Jerry Penacoli asked how he was adjusting to life as a single man.

"It's not something you adjust to," DeVito said ... adding, "Rhea and I are really close. Actually, still together, just separate, but together.”

When asked if there was a chance of a reconciliation, Danny revealed, "We're working on it."

DeVito and Perlman separated back in October ... but appeared at an airport together a few weeks ago ... the first sign that their marriage still has a chance.
