The couple have been married for 13 years and are the parents of two children, but they have been living apart for several months after their marriage underwent the strain of Douglas' battle with throat cancer and Zeta-Jones' treatment for bipolar disorder.
Douglas thanked his wife in his Emmy Award acceptance speech in Los Angeles Sunday night, even though Zeta-Jones did not attend the event with him.
"We're working things out, talking, and we'll see how she goes," Douglas told People.com before the ceremony.
Douglas, 68, won the Emmy for his portrayal of entertainer Liberace in the TV movie "Behind the Candelabra."
