"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," a rep for the actress said. "The two have an amicable relationship and will remain friends. They ask that people respect their privacy during this time."
Last year, after becoming estranged from Cokas, McPhee, who stars on CBS' upcoming drama "Scorpion," was photographed kissing her "Smash" director Michael Morris, who's married to actress Mary McCormack.
McPhee, 30, and Cokas, 49, reconciled and were reportedly working on their marriage as recently as March. They have no children together.
