Watch Julie Chen act for the first time on 'NCIS: Los Angeles' -- exclusive

Julie Chen

(Robert Voets/CBS)

Julie Chen is incredible at playing Julie Chen. She does it every day on The Talk. She does it every summer on Big Brother. And she has even shown off her range by playing Julie Chen on The Millers and Madam Secretary. Honestly, when it comes to playing Julie Chen, there are few better. Which is why it is time for the Chenbot to finally branch out and play non-Chen parts.

Chen’s next step towards total TV domination begins on Jan. 19 when she guest-stars on NCIS: Los Angeles as…U.S. Ambassador Nancy Kelly. And not just any U.S. Ambassador, but the U.S. Ambassador to Tunisia. And not just any U.S. Ambassador to Tunisia, but a U.S. Ambassador to Tunisia that has narrowly escaped a terrorist attack! The tension—it builds!

And now you can catch an exclusive glimpse of Chen’s performance as she comes face to face with Chris O’Donnell and LL Cool J so they all can get to the bottom of this dastardly deed. Prepare yourself for lots of emoting and hand-shaking as you feast your eyes on the video player below.
