The sheer shock of this homewrecking kiss seen ’round the world continues to rattle Hollywood!
An insider close to Kat is revealing just how bad it's been since the the lip-lock from hell was exposed:
"This is a very hard time for her. She's very upset."
Michael has three children with his actress wife, Mary McCormack—and reports have been surfacing the couple's headed for an ugly divorce since the photo was released!
"Katharine cares about Michael. But she still cares about Nick too. She didn't mean for anyone to be hurt."
We're thinking Miz McPhee's peeps need to have a chat with KStew's PR team!
Let's hope this blows over fast for all involved!
