Maybe Charlie Sheen really is getting serious about losing his bad boy persona.

An insider tells E! News exclusively that the former Tiger Blood-infused warlock has parted ways with his personal assistant/party buddy Rick Calamaro.

The move, which went down within the last couple weeks, is part of a broader effort by Sheen to "clean house" as he prepares to launch his new Anger Management sitcom next year. "Charlie thought Rick was a bad influence," says the insider.

How bad of an influence?

Rick, 50, a former Hollywood nightclub owner, met the actor in 2006 and in 2010 joined Camp Sheen full-time as an assistant. Rick was reportedly by Sheen's side for many of his legendary antics in Vegas, L.A. and New York.

A rep for Sheen has no comment; so far we have not been able to reach Rick for comment.
