Nicole Richie is plotting a return to primetime, this time as the star of a scripted comedy.

The one-time “Simple Life” celeb is headlining a single-camera half-hour sitcom in development at ABC.

The script, which is being produced through Sony Pictures TV, would feature Richie as a professional woman with complicated family relationships and struggling to figure out what role she’ll take as her life and her family evolve.

Daisy Gardner (“Californication”) is set to write the comedy; Warren Bell (“According to Jim”) will exec produce and supervise the pilot script. Jamie Tarses is attached as an exec producer.

Richie had the initial idea for the show. She’ll get a producing credit in addition to starring. Michael Baum of Impression Entertainment is also a producer.

Richie’s TV credits include NBC’s “Chuck.” She’s also guested on “8 Simple Rules,” “American Dreams” and “Eve.” She starred with Paris Hilton in “The Simple Life,” the semi-scripted reality show for Fox that played like a sitcom.

Separately, Richie is working on her second novel, as well as the debut of her clothing collection and shoe line.
