DeVito, 68 and Perlman, 64, have been quietly working on their relationship in recent months and have called off their separation. "They love each other," a friend of the couple told the magazine. "Always have and always will."
The couple, who first started dating in 1971, married in 1982 and have two daughters, Lucy and Grace, and one son, Jacob, together. Over the years, the actors played a couple on the TV show Taxi, and also co-starred in the 1996 film adaptation of Roald Dahl's Matilda.
