Michael Douglas and Catherine Zeta-Jones were reportedly holding hands at dinner last week.
The couple announced they were separating in August 2013, after 13 years of marriage.
But it looks like things between the two are definitely on the mend, according to E! News.
The outlet reports that Michael and Catherine had dinner last Tuesday night in New York at NYY Steak. Although it was apparently a private business meeting, the pair were said to be very affectionate with one another.
"Michael introduced Catherine to his guests as his wife," an onlooker told the website. "They were very sweet and very kind to the staff and they were definitely having a good time together."
Both Michael and Catherine were apparently wearing wedding rings.
Michael, 69, has often spoken about his marriage and how he hopes it can be salvaged.
"I hope to resolve my marriage in a positive fashion," Douglas said to GQ in December 2013.
The actor is very dedicated to his children as well, and says family life is the most important thing to him.
“We’re doing good, ya know, one day at a time… we are married, so there’s no big new announcement or anything else like that, but things are working out very nicely,” Michael told Extra in January.
“It always makes it easy when both people want it to work out.”
The couple have apparently been sharing their feelings on a daily basis in personal diaries, and this has reportedly helped them communicate better.
"They've been working on different ways to express feelings - including daily journals. They only show them to each other if things get bad - it's a way of giving them an outlet," a source revealed to British Grazia magazine.
