Mary McCormack \"Devastated\" Over Alleged \"Smash\" Affair

(Undated) -- Actress Mary McCormack is said to be devastated and "beyond furious" over reports that her husband, TV director Michael Morris, has been seeing "Smash" star Katharine McPhee on the side. A source tells gossip site "Life & Style" that McCormack, who starred in USA Network's "In Plain Sight," only found out about the affair this week - and just shortly before TMZ posted pictures of Morris and McPhee kissing in broad daylight. She reportedly wants out of their ten-year marriage but Morris is said to be sorry and trying to save it. The couple has three daughters together.

McPhee, meantime, is reportedly separated from her husband of five years, producer Nick Cokas. Insiders say the Season Five "American Idol" runnerup split from Cokas in March, months before she started seeing Morris. NBC canceled McPhee and Morris' musical drama "Smash" earlier this year.
