Another Hollywood Actress has been caught kissing her married director.

Katharine McPhee was photographed kissing her former "Smash" director Michael Morris in public on Sunday, stirring buzz considering the fact that both of them are married to other people.

In photos obtained by TMZ, the actress and Morris were caught in a lip-lock (PHOTOS) after their lunch date at I Panini Di Ambra in Hollywood on Oct. 22, E! News reported. The duo were reportedly holding hands and sharing several kisses in the parking lot.

McPhee reportedly did not appear to be wearing her wedding ring during the outing with Morris. The gossip site reported the duo are dating, despite the fact that they're both married to other people.

The 29-year-old "American Idol" runner-up has been married to 47-year-old performer and producer Nick Cokas in Beverly Hills since Feb. 2, 2008, after two-year engagement. McPhee and Cokas first met in 2005 when they performed in a L.A. production of "The Ghost and Mrs. Muir". 

Morris is married to Broadway actress Mary McCormack. The duo, who has been married for more than a decade and are parents to 9-year-old Margaret, 6-year-old Rose and 2-year-old Lillian. 

The status of Morris and McCormack 's marriage remains unclear, but a source close to McPhee and her husband confirmed to Life & Style magazine that the couple have "been separated for six months."

"Nick continues to co-manage her music," the insider added.

McPhee said earlier in the year that Cokas put starting a family on hold.

"I once thought that by now I'd have lots of children, but actually I'm really enjoying being able to go from point A to point B and the only worry I have is have my dogs been walked," she said. "I'm selfish right now, but that's how and where I should be. The thing is, work is the thing I love the most." 

The stars met on the set of the NBC musical drama, which was canceled back in May.
