Katharine McPhee Files For Divorce From Nick Cokas

It looks like there won't be a happy ending for Katharine McPhee and Nick Cokas, after all.

"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 "Smash" actress told People magazine. "The two have an amicable relationship and will remain friends. They ask that people respect their privacy during this time."

Earlier this year, it was thought that the couple may have reconciled, but that doesn't seem to be the case. The couple's marital problems first came to light after McPhee was photographed kissing married "Smash" director Michael Morris. At first it appeared as though both Morris and McPhee were cheating on their spouses, however, it quickly became apparent that McPhee and Cokas had already been separated for six months at the time news of the scandal broke.

A source close to the 30-year-old actress says no outside parties played a role in their final split. "It was just time. They'd grown apart and weren't right for each other anymore," the source told People.
