Date of Birth: August 25th 1981
Bilson attended a college in San Diego, but dropped out after one year, taking her father's advice to pursue a professional acting career and making several appearances in commercials, including advertisements for Raisin Bran and Pepto-Bismol. She made her screen acting debut in early 2003, appearing in episodes of Buffy the Vampire Slayer, 8 Simple Rules for Dating My Teenage Daughter, and in the short film, Unbroken. Bilson was subsequently cast in The O.C., which debuted in August of 2003. Her character, Summer Roberts, was initially intended to appear in only a few episodes, but became a series regular after a successful run, as Bilson's on-screen romance with Seth Cohen (Adam Brody) became a noted aspect of the series.
Bilson's first film role is in the The Last Kiss, a romantic comedy/drama also starring Zach Braff and Jacinda Barrett. In the film, which opened on September 15, 2006, Bilson plays a college student who seduces Braff's character. Bilson had long wanted to work with Braff, having admired the film Garden State, which he directed and starred in. A body double was used for the film's sexual scene between Bilson and Braff's characters, as Bilson specified that she "feel[s] really strong[ly]" about not appearing in a nude scene. One review of the film noted that Bilson played the role with "surprising depth", although another critic described her role as "Glenn Close in Fatal Attraction as an airhead valley girl with a hot bod".
