Perhaps it's not totally over between Danny DeVito and Rhea Perlman after all.

The pair, married for 30 years and one of Hollywood's most enduring couples, separated this fall. But DeVito, 67, now says it's not that simple.

"We're working on it," the It's Always Sunny in Philadelphia actor says of his marriage in an interview with Extra.

Asked how he's adjusting to single life, DeVito replied: "It's not something you adjust to. Rhea and I are really close. Actually, still together – just separate, but together."

DeVito married Perlman, best know for her role on Cheers, in 1982. They have a son and two daughters, all in their 20s.
