And here it is: DEMI MOORE announced yesterday that she's filing for divorce from ASHTON KUTCHER.   Here's her statement . . . "It is with great sadness and a heavy heart that I have decided to end my six-year marriage to Ashton. "  As a woman, a mother and a wife there are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life.   "This is a trying time for me and my family, and so I would ask for the same compassion and privacy that you would give to anyone going through a similar situation."   That line about "values and vows" obviously suggests Demi bailed because of Ashton's RESTLESS GROIN SYNDROME. Ashton, not surprisingly, posted his reaction on Twitter. He said, quote, "I will forever cherish the time I spent with Demi. Marriage is one of the most difficult things in the world and unfortunately sometimes they fail. Love and Light, AK."
