Charlie Sheen Returns To CBS Sitcom

Charlie Sheen is back at work. The "Two and a Half Men" star returned to the set of his CBS sitcom Tuesday, a day after his arraignment in Aspen, Colorado, and just weeks after he voluntarily checked himself into rehab. TMZ.com says while seeking treatment, Sheen will shoot the final four episodes of the season for "Two and a Half Men" in the day time, and return to rehab at night. Sheen pled not guilty Monday to a felony charge of menacing and misdemeanor charges of assault and criminal mischief. The charges stem from a Christmas Day altercation with wife Brooke Mueller who told police that the actor pulled a knife on her and threatened to have her killed when she said she would divorce him. The court set a trial date for July 21st. Sheen could face up to three years behind bars if convicted.
