Demi Moore is ending her 6-year marriage to Ashton Kutcher, she told The Associated Press.
The Hollywood power couple's relationship became tabloid fodder in recent months as rumors swirled about Kutcher's alleged infidelity.
"It is with great sadness and a heavy heart that I have decided to end my six-year marriage to Ashton," Moore, 49, said in a statement to the AP. "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."
Kutcher, 33, said in a response on Twitter, "I will forever cherish the time I spent with Demi."
The "Two and a Half Men" star added: "Marriage is one of the most difficult things in the world and unfortunately sometimes they fail. Love and Light, AK."
The pair frequently used Twitter to communicate with each other as millions of fans followed along — even amid rumors of Kutcher's infidelity. The day before their sixth wedding anniversary, Moore ominously quoted philosopher Epictetus: "When we are offended at any man's fault, turn to yourself and study your own failings. Then you will forget your anger."
Moore and Kutcher created the DNA Foundation, also known as the Demi and Ashton Foundation, in 2010 to combat the organized sexual exploitation of girls around the globe. They later lent their support to the United Nations' efforts to fight human trafficking, a scourge the international organization estimates affects about 2.5 million people worldwide.
The ex-couple wed in September 2005.
Moore was previously married to actor Bruce Willis for 13 years. They had three daughters together — Rumer, Scout and Tallulah Belle — before divorcing in 2000. Willis later married model-actress Emma Heming in an intimate 2009 ceremony at his home in Parrot Cay in the Turks and Caicos Islands that attended by their children, as well as Moore and Kutcher.
