"In light of continuous speculation over the lives and marriage of Tea Leoni and David Duchovny, the couple has confirmed that they have in fact been separated for several months," the statement says. "The couple had hoped to keep this separation private for the sake of their children."
Duchovny, 48, has been married to actress Leoni since 1997. They have two children, daughter Madelaine West, 9, and son Kyd, 6.
The actor voluntarily entered rehab last summer "for the treatment of sex addiction," he said in a statement issued in August.
Earlier this month, Duchnovny had "successfully completed the rehab program," his lawyer said. Duchovny was then spotted with Leoni at the Czech Street Festival in Manhattan.
