Demi Moore is filing for divorce from Ashton Kutcher, she told the Associated Press.

“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,” she told the news service.

Kutcher tweeted a statement, writing, “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.”

The news marks the end of weeks of speculation as to the couple’s status after rumors spread in September after a San Diego woman’s detailed account of an alleged sexual tryst with the 33-year-old Kutcher led to widespread reports that Kutcher and Moore were splitting.
