Nicole Richie on 'Chuck' -- VIDEO PREVIEW

Check out this video clip of Nicole Richie doing some major butt-kicking during her guest appearance on NBC’s hit show Chuck. The episode airs on Monday, October 20 @ 8PM ET/PT on NBC.

Here’s the episode synopsis: Chuck (Zachary Levi) learns more about Sarah’s (Yvonne Strahovski) past when they run into her old high school nemesis Heather Chandler (guest star Nicole Richie). Sarah’s teenage insecurities come to surface and she tries to avoid Heather at all costs. Chuck, on the other hand, does everything he can to hear more about Sarah’s hidden life. When Heather’s nerdy husband Mark (Ben Savage) turns out to be a key player in a new mission, the agents must attend Sarah’s high school reunion to prevent the sale of potentially dangerous super-bomber plans — all the action ends with the ultimate cat fight. Meanwhile, Big Mike (Mark Christopher Lawrence) leaves town for a day and Buy More’s new assistant manager Lester (Vik Sahay) decides to implement a new sales policy.
