Oh, how her nerd herd will grow.

Olivia Munn, who rose to Internet fame among fanboys while hosting G4's Attack of the Show — a gig that saw her roam the floors of Comic-Con dressed as Princess Leia and chomp down on all manner of sausage and cucumber on-air — has scored a role on NBC's Chuck.

Munn will play "an impossibly cool, smart, and pretty CIA agent who intimidates and schools Chuck and Morgan in the Season 4 premiere," according to Entertainment Weekly, which first reported the news.

The 30-year-old actress' job commitments are growing at a breakneck pace: Jon Stewart recently named Munn his "senior Asian correspondent" on Comedy Central's The Daily Show; this fall, she'll star in the NBC ensemble comedy Perfect Couples; and she's currently out on tour promoting her collection of personal essays, Suck it, Wonder Woman! The Misadventures of a Hollywood Geek.

This week, she'll be down at Comic-Con co-hosting G4's live coverage of the convention. No word yet on whether she plans to continue on Attack of the Show, which she has co-hosted with Kevin Pereira since 2006.

Munn most recently appeared in the films Iron Man 2 and Date Night. She has also guest-starred in Accidentally on Purpose and Greek.

The fourth season of Chuck premieres Monday, Sept. 20 at 8/7c.
