Isla Fisher has signed on to star in Confessions of a Shopaholic, Touchstone's comedy based on the novels by Sophie Kinsella, according to The Hollywood Reporter. Jerry Bruckheimer is producing, while P.J. Hogan is on board to direct.

The script, whose most recent draft was written by Tim Firth, centers on a compulsive shopper in Manhattan up to her neck in debt who ironically becomes a financial advice columnist.

Confessions of a Shopaholic is the first title of the book series, of which five have been published. In the U.K., where the series originated, the first novel was titled The Secret Dreamworld of a Shopaholic. Kinsella is the pen name for Madeleine Wickham, a U.K.-based financial journalist.

The production is scheduled to start filming in January.
