Los Angeles , California ( CNN ) -- Actor Charlie Sheen cited `` irreconcilable differences '' when he filed for divorce from Brooke Mueller Monday afternoon , a marriage that apparently hit the rocks when he was arrested last Christmas Day . Sheen listed December 25 , 2009 , as their date of separation and the day their twin infant sons began living solely with him . The couple married on May 30 , 2008 . The divorce petition , filed in Los Angeles County Superior Court , requested jointed legal and physical custody of Bob and Max Sheen , the boys who were born to the couple on March 14 , 2009 . Sheen was arrested on felony domestic violence charges after Mueller called police to their holiday home in Aspen , Colorado , last Christmas . She claimed he held a knife to her throat and threatened to kill her , the police report said . The felonies were reduced to a misdemeanor third-degree assault count in exchange for his guilty plea in August . The plea deal allowed his time in a a Malibu rehab center to count for his 30-day jail term . Sheen 's three-month probation is set to end Tuesday . He signed the divorce petition Monday morning , just six days after New York police reported finding him `` emotionally disturbed '' in a hotel room . Sheen was briefly hospitalized for what his representative said was an allergic reaction to medication . The New York incident led to tabloid speculation that Sheen 's mental and physical health was in danger , but his publicist Stan Rosenfield sought to shoot down the reports . Rosenfield shared with CNN an e-mail he received Sunday from Sheen manager Mark Burg , describing the reports as `` complete bulls -- t fabricated lies ! ! ! '' `` Charlie is fine and will be at work on Tuesday , '' Burg wrote . The son of actor Martin Sheen , Charlie Sheen signed a contract last summer to continue with his hit CBS sitcom `` Two and a Half Men . '' CNN 's Brittany Kaplan contributed to this report .
