Time has not yet healed the wounds between Charlie Sheen and Warner Bros., the producer of "Two and a Half Men." According to The Hollywood Reporter , the studio's lawyers have sent him a cease-and-desist letter over his recent use of publicity photographs taken during his stint on "Two and a Half Men."

Warner Bros. is miffed that at least two such pictures were distributed last month at a National Association of Television Program Executives conference in Miami, where Sheen promoted his upcoming FX comedy, "Anger Management." One of the pictures depicts Sheen wearing shorts and a leather jacket while posing on a motorcycle.

Warner Bros. warned Sheen, FX and "Anger Management" producer Debmar-Mercury in its letter, "That you are using Warner's intellectual property for a commercial purpose - namely, to sell another show - is especially egregious." The letter demands that they "immediately cease and desist" from using the photographs. A source close to "Anger Management" says, "It won't happen again."After receiving the letter, Sheen couldn't resist the opportunity to take a dig at his old bosses. He told  TMZ.com , "I'm thrilled. It insulates me from having to redundantly see myself in the idiotic bowling shirt. Perhaps if Warner Bros. spent as much time and energy focusing on THEIR show, it wouldn't be such a steaming pile of a**."

Last September, Sheen and Warner Bros. settled the 100-million-dollar lawsuit he filed after he was fired from "Two and a Half Men." "Anger Management" premieres in June.
