Demi Moore and Ashton Kutcher are reported to have parted ways after six years of marriage.
The divorce follows months of media rumours that the couple's relationship may have been in trouble - fuelled by reports of a San Diego woman claiming to have had an affair with Kutcher.
Moore's publicist issued a statement from the actress on November 18 (local time) that asked for "the same compassion and privacy that you would give to anyone going through a similar situation".
The statement read: "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."
Shortly after the statement was released, Kutcher tweeted a statement through his validated account that contained a number of poignant comments.
Through the @aplusk channel, Kutcher wrote: "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 couple were married in 2005 when Kutcher was beginning to enjoy success as an actor on the TV comedy That 70s Show.
Moore, 49, was previously married to well-known actor Bruce Willis, 56, for a total of 13 years and has three children with the Hollywood star.
Prior to that she was married to American rock musician Frederick "Freddy" Moore from 1980 to 1984 - the actress took his surname as her professional name, formerly being known as Demi Gene Guynes.
Kutcher is well known for his hosting duties on the celebrity prank show "Punk'd," and has recently taken on a role in the popular comedy Two and a Half Men, in light of Charlie Sheen's absence.
With two highly successful actors such as Moore and Kutcher there remains the question of how divorce financial settlements will affect their assets.
It is unknown at this time if the former couple had a prenuptial agreement in place before they were married - if they do not then there is a chance that the famous pair will undergo an even 50 per cent split according to the applicable laws.
In Australia there are legal guidelines in place that help to guide the division process - in some cases partners are able to reach their own agreements and do not need to submit to a court for arbitration.
However, family law advice is still a vital part in the process, helping to ensure that each party - including any dependents - are looked after by the final arrangement.
