Robert Harling has been tapped to pen Sony’s Reese Witherspoon starrer “The Pioneer Woman.”

Based on the upcoming book by Ree Drummond, “The Pioneer Woman: Black Heels to Tractor Wheels — A Love Story,” the film adaptation will tell the story of an young woman who, after falling for a cowboy, gives up her life in the city to live in Oklahoma.

The book, which hits selves in February, is an expansion of Drummond’s blog, which she started in 2006.

Harling’s previous writing credits include “Steel Magnolias,” “First Wives Club” and “Soap Dish.” His next project will be the Darren Star-produced dramedy based on the book “Good Christian Bitches” at ABC.

Laura Ziskin and Pam Williams will produce.

Witherspoon has been attached to the project since March.
