Making a quick stop for fuel, Mischa Barton and her boyfriend Sebastian Knapp filled up their car in Studio City, California on Tuesday (January 15).

The “O.C.” star looked cute in a gray sweater, orange skirt, and black and tan flats as she carried her paperback in one hand while her beau took over fueling.

Though she’s currently between film projects, fans can soon catch her in the upcoming drama “Bhopal: A Prayer for Rain.”

Based on actual events, the movie tells the interwoven stories of people in India and US as they face dilemmas of life time in the months leading to the biggest Industrial disaster in human history that claimed 10,000 innocent lives within a few hours.
