Actress Mary McCormack threw straying husband Michael Morris out of their Los Angeles home Sunday night after he revealed to her that photos of him smooching younger â€œSmashâ€ star Katharine McPhee were about to break online, sources exclusively tell Page Six. Morris, who directed McPhee on NBCâ€™s failed musical series, knew the photos were about to hit because, a source adds, he tried to buy them himself to keep them from ever being seen by the public â€” and thus ruining his marriage and reputation. But the horny hubbyâ€™s bid was unsuccessful, and TMZ posted the images of him and sexy McPhee enjoying an illicit lip-lock in broad daylight in a Hollywood parking lot. â€œMary 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,â€ said an insider. It wasnâ€™t the only bad news for McCormack, the mother of Morrisâ€™ three young children, over the weekend: NBC also canceled her new series, â€œWelcome to the Family,â€ after just three weeks on the air due to dismal ratings. Meantime, McPhee, 29, and her husband, Nick Cokas, 47, have been married since 2008, but reportedly have been amicably separated for months. A source close to former â€œAmerican Idolâ€ star McPhee said that after â€œSmashâ€ 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. Reps for McCormack, Morris and McPhee, and Cokas did not return requests for comment. McCormack previously starred in USAâ€™s â€œIn Plain Sight,â€ and she and Morris, her husband of 10 years, split their time between LA and Albuquerque while she starred on the show. Beyond his â€œSmashâ€ credit, Morris was a producer on ABCâ€™s drama series â€œBrothers & Sisters,â€ featuring McCormackâ€™s actor brother Will McCormack.
