Sporting a black derby hat with oversized shades, Rachel Bilson was spotted as she prepared for departure at Los Angeles International Airport on Saturday (September 27).

The former "OC" starlet smiled as she made her way past security, offering up an especially big grin as an airport employee gave a good look at her driver's license before letting her pass through.

Miss Bilson is on her way to Miami before going to Salt Lake City, Utah, as she readies to begin filming her new movie "Waiting For Forever" on Monday (September 29).

The James Keach directed film centers on "a young man who's happy without a job and decides to spend the rest of his life with his love - a 25-year-old TV actress living in Hollywood."
