Danny DeVito Surfaces 'Everything's Good'

For the first time since he separated from his wife, Danny DeVito appeared in public this weekend ... and told TMZ he's doing OK in the wake of the split.

A freshly bearded DeVito was lunching with some friends in Malibu -- sans his estranged wife Rhea Perlman -- and when we asked how things have been going since the announcement, he gave us a big thumbs up and told us, "Everything's good."

DeVito and Perlman split up earlier this month after 30 years of marriage -- though no divorce papers have been filed ... yet.
