Rep: Charlie Sheen hospitalized for "allergic reaction" to medication

Sheen and Mueller, his third wife, were married in May 2008. They have twin sons. Sheen is seeking joint custody.

The split comes less than a week after the Two and a Half Menactor was hospitalized in New York. His rep told TVGuide.com that Sheen suffered an "adverse allergic reaction" to medication, though a law enforcement official told the AP that Sheen checked himself into a hospital for a psychiatric evaluation after a woman told police he threw furniture in his hotel room.

Reps for Sheen did not immediately respond to TVGuide.com's request for comment.
