Look's like someone's caught McPheever! The musical series Smash was cancelled by NBC earlier this year after just two seasons. But star Katharine McPhee has kept in touch with the show's director -- very close touch. 

The 29-year-old former American Idol runner-up and Smash director Michael Morris were recently caught k-i-s-s-i-n-g by photographers.  The lip-lock quickly went public, thanks to the folks at TMZ.com.

Here's the trick: Both Morris and McPhee are currently married--to other people.

McPhee has been married to 47-year-old producer Nick Cokas since 2008, though sources claim the couple has been separated for the past six months.

Morris has three children with film and TV actress,  Mary McCormack (Private Parts, In Plain Sight). No word on whether Morris and McCormack have been experiencing similar marriage woes.

An agent for Morris and a rep for McCormack both declined to comment, but People.com quotes a source close to the couple as saying: "Mary adores her husband. If this is true, she would have been blindsided."

McPhee's camp also declined comment.
