The Broadway-themed series 'Smash' was canceled after its second season, but that hasn't stopped the former cast member (and 'American Idol' alum) Katharine McPhee and the show's director Michael Morris from keeping things going...in real life, at least. McPhee has split from her hubby of five years and is now dating Morris, who is married with three kids.

What a mess! Or so it seems...

McPhee, 29, and actor/producer Nick Cokas, 48, met in 2005 and wed in 2008. They split in the spring. But it appears to be amicable, as Cokas, who is 19 years older than his wife, remains involved in her career. A source said, "They've been separated for six months. Nick continues to co-manage her music." Yeah, that has to be awkward.

McPhee, who once called Cokas "the love of my life," and Morris were snapped smooching in public. Their PDA was pretty public.

It's scandalous since he is wed to actress Mary McCormack, with whom has has three daughters, ages 2, 6 and 9. Perhaps that marriage was on the outs or is on the outs now that the photos are splashed all over the media.

The photo of McPhee and Morris sucking face is here. We call that "Not Even Trying to Hide It" or "We're in love and we don't care who knows!"
