Look for Rachel Bilson to guest-star as a potential love interest on the new NBC comedy, "Chuck."

NBC announced yesterday that the former O.C. star has agreed to sign on for multi-episodes on the series, scheduled for broadcast in late October. Bilson will play the first romantic possibility for Chuck (played by Zachary Levi), since his college girlfriend broke his heart a few years back.

Says Josh Schwartz, series co-creater and executive producer:

"Rachel's been traveling all over the world shooting a big Doug Liman action-movie, 'Jumper,' and she was going to be in Los Angeles for a little while. We were talking and thought it would be fun to work together again, even for a few weeks. Having worked with her for four years, I know how funny Rachel is and what a good match she'd make for the show, and for Zach Levi. For a first-year series, it's really hard to get big-name guest stars, so we're all really excited and grateful that she could do this."
