Real-Life Couples of ‘The O.C.’: Ben McKenzie, Mischa Barton, Adam Brody & More
The O.C is the place with some of our favorite early 2000s couples — notably Ryan and Marissa and Seth and Summer — and it turns out those couples were real off-screen, too! We've always adored the budding romances between the stars on the teen drama, wondering whether the relationships would last through high school chaos.

See what happened behind-the-scenes with these stars, plus more about the relationships of The O.C. actors from the Warner Bros teen drama.
Ben McKenzie and Mischa Barton: From on-screen drama to real-life romance
Characters Ryan Atwood and Marissa Cooper were the couple everybody wanted to be in the early 2000s, but as it turns out, the actors playing them started dating behind-the-scenes, too. Mischa Barton, then 17, recalled on a podcast that when they dated, he was 25.
Yeah, it wasn't just on screen either ," Barton explained. "I mean it was kind of complicated for me. I went into that like a virgin, like a kid, like really feeling like I needed to grow up quickly...That was my first (relationship). I had no idea what I was doing."
Adam Brody and Rachel Bilson: Seth and Summer IRL
Adam Brody and Rachel Bilson were another on-screen couple from The O.C. that bled into real life. Seth Cohen and Summer Roberts coupled up on the show and it seems that's what started their real-life relationship.
Bilson realized she might have feelings for Brody after their first on-screen kiss in season 1. " I remember after shooting the scene where I kiss him, like, I remember thinking, 'Do I like Adam?'" she said in her podcast. "That's when those wheels started turning."
After their characters, Seth and Summer, coupled up on-screen, Brody and Bilson began dating in real life in 2003 and remained together throughout most of the show's run. But in 2006, while filming the fourth and final season, the couple broke up, though they remain friendly to this day. Brody and Bilson even ran into each other in the airport in 2019 and shared a photo on Instagram. " I got on a plane leaving New York to head to L.A., and someone taps me on the shoulder," Bilson explained. "I turned around and it's him. I was like, 'Oh my God, Brody!' It was just so good to see him."
