After 13 years of marriage, Michael Douglas and Catherine Zeta Jones are reportedly set to announce they are divorcing! It's true, we have not seen these two photographed together in months, and sources tell The Mirror it's Michael who will be announcing the news as Catherine is fighting to save the marriage! A rep for Douglas is neither confirming or denying the reports. No doubt these two have faced several challenges recently--Michael's 2011 throat cancer diagnosis and Catherine's battle with bipolar disorder. We will keep you posted as the news becomes confirmed.
