Married Katharine McPhee caught kissing married man who is not her husband

It seems love was in the air on the set of “Smash.”

Katharine McPhee, who appeared on the now-canceled show, was photographed kissing the show’s former director Michael Morris.

So what’s the big deal? After all, they’re both married.

Just not to each other.

Morris is married to actress Mary McCormick and McPhee is married to Nick Cokas. Sources told TMZ McPhee and Cokas have been separated for about six months.

Morris and McCormick have been married since 2008 and have three children.
