Katharine McPhee has filed for divorce from husband Nick Cokas after six years, her rep confirmed.
Katharine, 30, separated from Nick, 47, when she was spotted kissing her married “Smash” director Michael Morris in October last year.
Morris has been married to actress Mary McCormack for more than 10 years.
McPhee’s publicist told People, “After six years of marriage, and having been separated for the past year, Katharine McPhee has filed for a dissolution of marriage from Nick Cokas.”
