When Katharine McPhee's make-out session with director Michael Morris surfaced online, it had a lot of people talking -- but probably none more than Michael's wife, actress Mary McCormack.
Life and Style magazine says Mary was "furious" and "absolutely devastated" to discover that her husband was having a relationship with the young actress, whom he directed in the series Smash -- and now she wants to end their marriage. An insider says, "They've been together for more than 10 years and always had such a solid marriage. They have three daughters, so it's incredibly sad. He wants to keep the family together, but as far as Mary is concerned, it's over. There's no going back."
Katharine ended her relationship with Nick Cokas, her husband of five years, in March -- before she started a relationship with the director.
It hasn't been a good week for Mary -- NBC just cancelled her new show, Welcome to the Family.
