After intense media speculation about the mental state and marital situation of Charlie Sheen, the actor has filed for divorce from Brooke Mueller, his wife of two and half years. The couple has two sons, Bob and Max, who are 21-month-old twins.

Sheen and Mueller were married on May 30, 2008. The following March, Mueller gave birth to the couple's twin sons. Although Sheen has had a history of failed marriages and allegations of domestic violence, his marriage to Mueller seemed to be a happy one, and the family stayed largely out of the public eye until late 2009.

On December 25, 2009, Colorado police were called to a home in Aspen, where Sheen, Mueller and their sons were spending the holidays. According to police reports, Mueller claimed that Sheen had held a knife to her throat and threatened to kill her. Sheen was subsequently arrested on felony domestic violence charges.

In August of this year, Sheen pleaded guilty to a reduced charge of misdemeanor third-degree assault. He was sentenced to 30 days in jail, but struck a plea deal that allowed him to serve his time in a Malibu rehab center instead of prison. His three-month probation ended this week.

Sheen filed for divorce early this week in Los Angeles Superior Court, citing irreconcilable differences as the reason for the couple's split. According to the petition, he and Mueller were separated on the date of the Aspen incident, and have been living apart for almost one year. In the divorce filing, Sheen requested joint physical and legal custody of young Bob and Max.

The divorce filing comes at an interesting time for Sheen. He was reportedly hospitalized last week after he suffered an alleged allergic reaction to medication that caused him to trash a New York hotel room. Sheen's representatives have repeatedly dismissed claims that the actor's physical and mental health are in danger, and Sheen has been back at work this week shooting his hit television show "Two and a Half Men".
