Sarah Jessica Parker is to trade her designer dresses for the life of a lone parent in an adaptation of the novel The Ivy Chronicles.

The Sex and the City star will play a high-powered New York executive in the comedy, who begins anew after she loses her Wall Street job, divorces her cheating husband and moves out of her Park Avenue flat. To provide for her two daughters, she sets up a business helping Manhattan's elite how to get their offspring in premier kindergartens.

Screenwriter Aline Brosh McKenna has just been hired to adapt the bestselling novel by Karen Quinn. Brosh McKenna is a specialist in the comedy genre as she has penned the screenplays for The Devil Wears Prada, this year's 27 Dresses, and the 2004 comedy Laws of Attraction, starring Pierce Brosnan and Julianne Moore.
Parker could make The Ivy Chronicles her first film since Sex and the City the Movie hit cinemas earlier this summer. The adaptation of the hit TV series has been a hit with audiences and has so far cashed more than £185m around the world. Parker is also attached to star in another comedy, A Family Affair, in which she would play an engaged woman who realises a former one-night stand of her is her future father-in-law.
