Before Lucy Hale (Aria) was a Rosewood resident, she played the ultimate California girl on The OC. Lucy appeared in one episode as Hadley Hawthorne, Kaitlin Cooper’s (Willa Holland) best friend/roommate at boarding school. This role launched Lucy into teen TV and we’ve been obsessed with her ever since.

Watch the video of Lucy acting alongside Willa and Mischa Barton. She plays a valley girl and says “obvi” at least five times. It's the complete opposite of Aria, but trust us, Lucy is pretty entertaining.
