Charlie Sheen has hit another erratic spell and CBS has finally admitted they’re worried about the drug-addled star. Starting in October Sheen has been caught cavorting about in big cities like New York and Las Vegas hanging out with porn stars and doing insane amounts of drugs.

While he’s acted rather professional on set for the hit show Two and a Half Men, CBS entertainment chief Nina Tassler admitted that the network is growing more and more concerned.

“We have a high level of concern. How could we not?” Tassler said at the Television Critics Association press tour in Pasadena on Friday. “This man is a father. He’s got children. He has a family. So obviously there’s concern on a personal level.”

Tassler then goes on to say that Sheen always shows up for work and does a great job, so really, there isn’t too much the network would even want to do.
