Danny DeVito is "working on" getting his marriage back on track.

The 67-year-old actor and estranged spouse Rhea Perlman, 64, announced in October they were separating after 30 years of marriage, but now the Twins star has admitted he is still "really close" to the actress and they are hoping to get back together.

Asked about life as a single man, he told Extra, "It's not something you adjust to. Rhea and I are really close. Actually, still together, just separate, but together." Asked if they are getting back together, he added, "We're working on it."

The couple - who met in 1970 and tied the knot in 1982 - have not filed divorce papers and first sparked rumors of a reconciliation when they were seen together at Los Angeles International Airport last month.

Danny and Rhea met when she went to see off-Broadway play, The Shrinking Bride, which the actor was appearing in.
