'Chuck's' Zachary Levi On Guest Star Nicole Richie: 'She Was Very Grounded'

LOS ANGELES, Calif. -- The season premiere of "Chuck" is weeks away, but the show's star, Zachary Levi, has been hitting the red carpet promoting his highly anticipated return as a computer geek who has government secrets inside his head. The second season of "Chuck" will feature the return of Yvonne Strahovski as his handler of sorts, Sarah Walker, but as previously reported on AccessHollywood.com , another lovely lady is joining the cast, for one episode at least -- Nicole Richie.
