Katharine McPhee files for divorce

Katharine McPhee has filed for divorce from her husband of six years Nick Cokas.

Katharine's rep tells 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. The two have an amicable relationship and will remain friends. They ask that people respect their privacy during this time."

This news comes seven months after Kat was caught kissing the director of Smash Michael Morris.

I'm actually surprised it took them this long to split. Michael Morris' wife kicked him to the curb immediately when the affair went pubic.

Kat is starring in Scorpion on CBS in the fall.
