Fresh from her starring turn in "P.S. I Love You," Hilary Swank is turning her eyes to possibly starring in another book adaptation.

The Oscar winner and her producing partner Molly Smith have picked up the rights to "French Women Don't Get Fat," according to The Hollywood Reporter.

The 2004 nonfiction lifestyle book written by former Veuve Clicquot champagne executive Mireille Guiliano gives insight into why French women stay slender despite consuming wine, pastries and other foods dripping in butter. The book reached No. 1 on the New York Times nonfiction bestseller list and was translated into 40 languages.

The adaptation, penned by "Freaky Friday" scribe Heather Hach, will be a romantic comedy that centers on a "girl-next-door champagne company middle manager who learns some tough life lessons which help her become the woman she's always wanted to be." The project will be a possible starring vehicle for Swank.

Swank and Smith will produce through their Alcon Entertainment-based 2S Films, along with Aaron Geller and Darryl Porter of PorterGeller Entertainment.

2S is also developing "Falling Out of Fashion" and "You're Not You." Porter and Geller are developing a buddy-action comedy based on the TV series "Soul Train" for Warner Bros. and a biopic on the life and music of Miles Davis, which has Don Cheadle is attached to star and direct.

Hach, with the help of "Freaky Friday" novelist Mary Rodgers, is writing a "Freaky Friday" sequel.
