Report: Lindsay's Behaving Herself

According to a report in Wednesday's New York Post, Lindsay Lohan, who was once considered such a liability on any movie set that she had trouble getting work in the last year, has tamed her wild ways and is now the very model of a responsible actress on the set of her upcoming film, Labor Pains.

"She's showing up early," the Post quotes a source as saying. "She knows her lines and her co-workers actually like her... She's a total pro now."

And what could be behind this 180-degree turnaround in her behavior? According the paper, the producers should be thanking La Lohan's constant companion, DJ Samantha Ronson, who reportedly "has a calming effect on her."
