Ashton Kutcher on Thursday confirmed the end of his marriage to Demi More via Twitter.

"I will forever cherish the time I spent with Demi," Kutcher Twitted today.

"Marriage is one of the most difficult things in the world and unfortunately sometimes they fail. Love and Light, AK," he continued.

Also today, People Magazine confirmed the separation.

"It is with great sadness and a heavy heart that I have decided to end my six-year marriage to Ashton," says Moore in a statement, according to People. "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."

Moore 49, and Kutcher, 33 are making the announcement after reports that Kutcher had an affair with a 22-year-old woman on the couple's sixth wedding anniversary in September.
