Katharine McPhee SIGHted Making Out With Her MARRIED Smash Director!

Oh no. It’s happening again. A director is falling in love with his leading lady!

NBC might have canceled Katharine McPhee‘s show Smash but they can’t cancel whatever it is that’s going on between her and the series’ director, Michael Morris!

The two, who are both married to OTHER people, were caught making out in public this week!

What the WHAT?!

Morris is married to actress Mary McCormack, famous for playing Howard Stern‘s wife in Private Parts as well as starring for 5 seasons on her own show In Plain Sight. Together they have 3 young daughters.

Miss McPhee, 29, married 47-year-old producer Nick Cokas back in 2008. But insiders say the two have been separated for at least 6 months now!

But what about Michael and Mary? Is their love on the rocks as well??

Maybe Katharine and Michael can just play off this kiss as a misunderstanding. Like, they were rehearsing for a play, or he was giving her stand-up CPR!

Oh wait, they were also caught holding hands and cuddling with each other while hanging out in Hollywood…

Welp, the proof may be in the PDA!

Any advice for KatPhee for life after adultery, Kristen Stewart?
