Screenwriter says 'screwball comedy' spoofs celebrity obsession and is not taking a cheap shot at the troubled 'Mean Girls' actress.

Model Lydia Hearst has been cast in the comedy film Dogs in Pocketbooks as a wild-child character that the film's screenwriter Charles Casillo told the New York Post is based on troubled actress Lindsay Lohan.

"Lydia will play a bratty movie goddess in and out of rehab, in trouble with the law, and hounded by greedy agents, predatory paparazzi, off-the-wall stalkers and crazed media -- a role obviously based on Lindsay Lohan," Casillo said about his self-described "screwball comedy."

He describes Dogs in Pocketbooks as a spoof on celebrity obsession, and not a mean-spirited attack on Lohan. Twenty-six-year-old Hearst, who is heir to the Hearst publishing fortune and daughter of Patty Hearst, will star opposite Joan Collins.
