Can you say One and a Half Men?

With his personal life in shambles, Charlie Sheen is hinting that this may be his last season on the hit CBS series.

(On Christmas Day, the troubled actor was arrested on charges of domestic violence after a confrontation with wife Brooke Mueller. He's since entered rehab as a "preventative measure" and pleaded not guilty in court.)

As for his future on Two and a Half Men? Sheen's rep, Stan Rosenfield, simply told People Magazine:

"Charlie's deal is only through this current season."

Sounds ominous for fans of the show, but also sounds like a negotiating tactic. It's hard to see Sheen leaving millions on the table and walking away from television's highest-rated sitcom.

In its seventh season, Two and a Half Men earned three Emmy nominations last year, including a victory for co-star Jon Cryer.
