Where You’ve Seen Her: This brunette beauty is probably most famous for playing Summer Roberts on Fox’s The O.C. These days, she stars on a show all her own, Hart of Dixie, which returns for a third season on the CW this fall. She also has a recurring spot on How I Met Your Mother as the one-time roommate of the show’s titular Mother, and has appeared in movies like Jumper and L!fe Happens. This summer, you can catch her on the big screen in the star-studded comedy The To-Do List, in theaters tomorrow.
