Los Angeles ( CNN ) -- Two years after Demi Moore announced she wanted to end her marriage to Ashton Kutcher , their union is legally undone . Kutcher 's lawyer filed the document in Los Angeles County Superior Court Tuesday making their final divorce settlement official , according to a court spokeswoman . Kutcher , 35 , filed the divorce petition last January -- citing irreconcilable differences -- but Moore , 51 , made it clear in November 2011 that the marriage was over . `` It is with great sadness and a heavy heart that I have decided to end my six-year marriage to Ashton , '' Moore said in her announcement . Kutcher has been dating his former `` That '70s Show '' co-star Mila Kunis since early 2012 , although she initially denied a romantic relationship . He is one of television 's best paid performers thanks to the gig he got on CBS ' `` Two and a Half Men '' after Charlie Sheen 's implosion . Moore and Kutcher began dating in 2003 and married in September 2005 despite a 15-year age difference . In the wake of Moore 's announcement of their split two years ago , Kutcher tweeted : `` 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 separation , however , came amid reports that Kutcher cheated on his wife on the night of their wedding anniversary . `` 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 said at the time . `` 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 . '' This is Kutcher 's first divorce , but the third time for Moore . She was previously married to actor Bruce Willis and rock musician Freddy Moore . CNN 's Jane Caffrey contributed to this report .
Moore 's lawyer filed the final papers on Tuesday . They announced their separation 2 years ago . Kutcher 's been dating former ` ` That ' 70s Show '' co - star Mila Kunis since 2012 . The couple began dating in 2003 and married in June 2005 .
