Morris appears to be wearing a wedding ring.
A source has told PEOPLE that McPhee – who has been separated for six months from husband Nick Cokas – is "very upset" about the kissing photos being published and "didn't mean for anyone to be hurt."
"This is a very hard time for her," the source also said.
Morris and McCormack – who's appeared on In Plain Sight, The West Wing and most recently on NBC's Welcome to the Family – have three young children.
An agent for Morris and a rep for McCormack both declined to comment at the time when the kissing photos were published.
