Katherine McPhee ruins Michael Morris’ marriage?

OHMYGOSSIP — Katherine McPhee is officially a home-wrecker! The actress and singer was recently caught smooching her married Smash director Michael Morris.

And now, because of the public PDA, Morris’ wife, actress Mary McCormack, has thrown him out of their Los Angeles home. Mary told Morris to pack his bags after he revealed to her that photos of him with McPhee were going to break online.

“He knew the photos were about to hit because  he tried to buy them himself to keep them from ever being seen by the public,” a source said.

“Mary threw Michael out of the house on Sunday night when he told her that TMZ had the photos and that they were about to be released.”

Katherine McPhee, 29, and her husband, Nick Cokas, 47, have been married since 2008, but reportedly have been amicably separated for months.

McPhee said that after Smash was canceled, she headed from New York, where it was filmed, to LA so she could work on her fourth album, which is expected to be released next year. She apparently reunited with Morris there.
