Model Lydia Hearst will star as a wild-child character in the comedy Dogs in Pocketbooks.

According to The Hollywood Reporter, the film's screenwriter Charles Casillo said the film 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," Charles Casillo said about his self-described "screwball comedy."

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

No production date has been set.
