Rachel Bilson is sharing secrets about dating in the public eye. "[Adam Brody and I] were a couple on the show and a couple in real life, [fans are] like, 'Oh, it's Seth and Summer' and they really relate it to that," Bilson, 44, recalled on the Tuesday, January 20, episode of the "Let's Be Honest" podcast. "They think that's what you are [and] who you are." Bilson famously starred as Summer Roberts on The O.C. from 2003 to 2007, during which she sparked a three-year romance with Brody, who played her onscreen love interest.
