Lindsay Lohan has been working very hard on his new movie "Liz and Dick" Lifetime producing for television, and to "calm" stress smokes two packs of cigarettes a day.

"Literally, every time a scene ends, Lindsay lights another cigarette," says a source told Us Weekly. "You can hear people say in the set: 'Get a cigar for Lindsay.'"

"In between takes he would sit in the director's chair smoking his cigarettes. Has been working very hard, but without nicotine probably could not do it, that keeps it quiet," adds the source.

However, it is reported that Lifetime executives worried go for fear that the continuing problems of Lindsay ruining the filming of the tape.

Producers are particularly upset by the automobile accident a few weeks ago. They fear that LiLo's probation could be affected by lying to police, and worry that the actress a car crash again.
