Michael Douglas and Catherine Zeta-Jones fuelled rumours of a reconciliation after they were photographed spending time together over the Christmas holidays.
The Hollywood stars announced their separation over the summer, but they reunited at Halloween to take their two children trick-or-treating.
Douglas was forced to play down rumours of a reconciliation back in October, but the former couple has now fuelled gossip about the state of the marriage after they were spotted together in New York City over the holidays.
They were seen walking through Manhattan with their children, Dylan, 13, and Carys, 10, enjoying a meal at a restaurant before taking in a showing of Broadway musical Motown.
The family outing ended with a trip to the movies to see The Hobbit: The Desolation of Smaug.
Both stars were wearing their wedding rings during the trip.
