Katharine McPhee and her husband Nick Cokas have quietly parted ways, and this happened long before her public smooch with Michael Morris.
"They've been separated for six months," a friend says of the couple, who got married over five years ago. "Nick continues to co-manage her music."
The news comes on the heels of reports that Katharine McPhee and Michael Morris, her former Smash director and who is also married, are together.
Morris' wife is actress Mary McCormack (In Plain Sight, Private Parts). They have three daughters, 2, 6 and 9. Katharine, 29, has no children with Nick.
Katharine and Nick Cokas first met in 2005 when they performed in a L.A. production of The Ghost and Mrs. Muir and soon began a romantic relationship.
